That requires an unbound lookahead which is better avoided.

The square bracket has a bit of history in go already, as a key-type
specifier for the somwhat generics-like map declaration;
since we already do
var map[int]string
it feels a bit natural to specify types in square brackets to me.

Hi
pipe character isn't exactly used anywhere in Go, is on every keyboard and
looks decent enough:
a, b = w | x, y | (z)
type Example |X, Y| struct { }
certainly not worse than square brackets with having advantage of not being
ambiguous to newbies or parser

Thanks for the answer.
Concerning only the current proposal, is there a reason why we shouldn't
allow specifying the parametric types for a whole bunch of functions /
types at once?
Like:
generic (type T) (
func Average(value []T) {...}
func Median(value []T) {...}
// etc
)
generic (type T1, T

Concerning the current generics proposal, was it every considered to not
allow type contracts at all?
No type contracts would mean that generic functions can only use =, & on
variables of parametric types, as these are always available for all types.
Nothings else is allowed.
This would remo

I don't know if the recommendation to use guillamets is out of spite for
the ongoing deliberations. But if it's a serious recommendation, then can
some recommend where I can buy one of these European keyboards? On top of
that, I could start a business selling European keyboards to Go programmers

I'm glad that the use of ( and ) is being reconsidered as I found their use
made *reading* source code with generics more difficult (albeit whilst
making parsing easier). One of the features of Go I really like is how
readable the source code is and every effort should be made to maintain

Can not agree any more. Compiler's job, it's duty, is to translate the
human readable code into binary 0 and 1. Human readability should take
precedence over the compiler complexity and even performance.

It is a serious suggestion. Our editors are flexible enough to allow us to use
control keys to generate these characters. Our ethnocentric, ASCII limited view
of programming languages would benefit from more flexibility when it increases
readability.

I don't think there's any real risk of guillemets ever being adopted. But since
this appears to be a serious proposal...

While I have over 50 years of programming experience, I am also quite old
and sometimes have senile moments.
I once wrote an extremely well-written bug report complaining about the use
of the backtick which is not on my keyboard, explained why it should not be
used, and then presented a workaro
The more I think about this suggestion, the more I like it.
- It solves the lookahead problem (I think);
- it visually separates the type parameters from the actual parameters and
return types, so the choice of delimiter characters for the type arguments
becomes less relevant from a readability
