Article about problems & suggestions for D 2.0

[Andrej Mitrovic]

Oh man wouldn't it be cool if we could use this syntax like this:

void test(R1:isInputRange, R2:isForwardRange)(R1 r1, R2 r2) {}

I'm not sure how that would work with multiple constraints or
constraints that need comparisons, e.g. ElementType:

void test(R1:isInputRange && ElementType == int, R2:isForwardRange)() {}

Just throwing ideas for D5 there.. lol.
