(1) Typeclass imports become "import impl". So you'd write "import impl
driver::diagnostic::handler" where you'd write "import
driver::diagnostic::handler" today. This way, when you look at a method
call and you don't know where it's coming from, you just grep for
"import impl" and look at all the implementations in scope.
(2) Change method calls to '->', like C++, Perl, and PHP. That operator
is free and it has precedent. And getting away from overloading the dot
worked well when we changed module access from '.' to '::'.
Thoughts?
A bit opposed to both, sadly. I quite like picking up impls "by
accident" via "import foo::*", and dislike the aesthetic of ->.
Is the ambiguity between field-access and method-call really biting in
actual cases? Users really seem to adore '.' as a sub-component
accessor. We even have people wanting us to go back to '.' for
module-separator :)
