I have no idea if this has been discussed yet, but I was thinking it would be neat to have benchmark blocks that only run when specified, like how unittest works.

Code:

benchmarks
{
 import std.conv : to;
 int a;
 void f() {auto b = to!string(a);}
 auto r = benchmark!(f)(10_000);
 auto f0Result = to!Duration(r[0]);
 writeln(f0Result)
}

Example:
rdmd -benchmarks -main myapp.d

Alternatively, the writeln could be replaced with some kind of standard benchmark output utility (similar to the idea of assert when used for unit tests).

Thoughts?

version(benchmark)
{
    ...
}
