DMD Compiler Version Dependent Conditional Compilation

[Nordlöw]

Can I use the version keyword or static if to perform conditional 
compilation  that depends on the version of DMD?

I typicall something like
version(>= DMD_2.0.66)
{
    // use new byChar, byWchar, byDchar, byCodepoint
}
else
{
    // use old style slower version
}

If so how?
