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?

@kind("benchmark") unittest
{
   ...
}
