Sometimes it's handy to have non-nesting comments.

For example, when debugging something, I sometimes use:
---
foo();
/*
bar();
/*
baz();
//*/
---
So I can quickly remove the first '/*' (by prepending '/') to uncomment bar() 
but not baz().

Also, Walter may feel differently about the C-compatibility thing than you do :).

That just sounds like a possible compiler optimization for
---
ulong L;
uint I;
// initialize L & I
auto result = cast(uint)(L / I);
