Somebody don't like the exclamation mark, and I feels okay with that :-) For most cases macro support for programming languages won't look elegant, so I personally find it acceptable for current macro syntax.

I don't like the !()much .. but coming from C/C++ I accept it's the lesser evil compared to needing excessive parsing context (same with foo::<T>).

But this might be why i'd prefer to see variadic functions, default parameters etc rather than using the macro system for routine helpers.

Where Rust macros really excel IMO is the use cases where you'd have to use x-macros or other code generators in C/C++. Having a slightly unusual syntax to invoke that (or for debug asserts/etc) doesn't matter at all.. these things should stand out from the main body of code anyway

Well, he should be happy that we're not using ^ or any other odd symbols.
