Hi,
Someone on IRC wanted to know the element type of an array type and the
following code was suggsted:
template ElementType(T : T[])
{
alias T ElementType;
}
He was confused about how ElementType!(int[]) could possibly equal int,
until we explained that the alias does, in fact, represent the 'result'
of the template.
So we started discussing whether a more intuitive syntax could be found.
Someone suggsted:
template ElementType(T : T[])
{
alias T template;
}
I personally believe this makes it perfectly clear that you're aliasing
the template itself to T.
Thoughts?
I like this `alias T template;` syntax.
`alias T ElementType;` is like writing `myFunction = value;` in function
`myFunction` instead of `return` statement.
This was exactly my thought too.
