I can imagine how you would define the constructor on the receiving type in Perl 6, but there's no "casting" syntax in Perl 6. Should we pretend there is for purposes of defining a conversion and allow:
class foo { ... sub prefix:IO::Socket(foo $f) returns(IO::Socket) {...} }
or did Larry mention a way to define a converter and I missed it?
From A12:
************************** New Grammatical Categories
The current set of grammatical categories for operator names is:
Category Example of use
-------- --------------
coerce:as 123 as BigInt, BigInt(123)
self:sort @array.=sort
term:... $x = {...}
prefix:+ +$x
infix:+ $x + $y
postfix:++ $x++
...
**************************It's not exactly clear how that's used, considering that you can't do multi-dispatch on the return type (right?)...perhaps like
multi sub coerce:as(Int $dest is rw, MyObj $src) {...}-- Brent "Dax" Royal-Gordon <[EMAIL PROTECTED]> Perl and Parrot hacker
