I just noticed this slightly odd behaviour from dmd -run and wondered if it's a "bug"?

[vertest.d]
import std.stdio;

void main()
{
  version(TEST) writefln("TEST");
}

If we compile without -run we get consistent/expected behaviour from -version:
  C:\TEMP>dmd vertest.d -version=TEST
  C:\TEMP>vertest
  TEST

  C:\TEMP>dmd -version=TEST vertest.d
  C:\TEMP>vertest
  TEST

But, if we use -run...
  C:\TEMP>dmd -run vertest.d -version=TEST  <- weird, outputs nothing

  C:\TEMP>dmd -version=TEST -run vertest.d
  TEST

Basically it looks like -run ignores any arguments that follow it..

It does not ignore, it passes them as an arguments to resulting program.
