Issue ID: 18543
Summary: Comments inside string mixin silently short-circuit
code

I have recently stumbled upon the following wrong behaviour inside string
mixins.
If you use a single line style comment (//) inside a string mixin, this will
silently short-circuit the code, leading to unexpected behaviour, as you can
see in the example bellow:
import std.stdio;
void main(string[] args)
{
mixin(""
~"writeln(\"Hello\");"
~"// Some comment"
~"assert(0);"
);
}
The assert will never get triggered.
If you use multi-line comments (/* */) those are correctly recognized and
everything works as expected.
