This syntax makes a lot of sense, but why have the '=' at all? Why
not just:
alias Num float;
alias MyFoo Foo!q{
};
Because then we have
alias symbol1 symbol2; which means symbol2 is an alias for symbol1 and
alias symbol1 symbol2!(...) which means symbol1 is an alias for
symbol2!(...). It does not seem right.
I guess one reason is that it fits better with the rest of the
language, it feels more natural. Also, wouldn't your proposal require
making the current syntax illegal and breaking pretty much all of
existing D code?
Every proposal here would break D, so I'm not sure what you mean by "my"
proposal. Also, because aliases are non-lvalue definitions, I don't
think '=' makes a lot of sense, but I'm not an expert on the matter.
No, they are all additive and backwards-compatible changes. (the old
syntax would persist as an alternative) And in D the lhs of a =
initializer is not required to be an lvalue anyway: enum x = 1;
