What you really need is a version statement based on the version 
of the D language, not the version of DMD or LDC or GDC per se.

Something like

version(DLANGSEMVER >= 2.076.0)
{
    //include static foreach code.
}

but we can't do conditionals in version blocks, so you'd need a 
static if. Alternately, we'd also need a trait or something to 
get the semver of the compiler.
