You compile it or detect AST-node presence.

And avoid standard libraries?

Javascript supports eval() so it can support string mixins in 
theory, even at runtime, but if you cannot easily translate the 
mixin content then you have a challenge.

Not that D is meant for web browsers, but my point is more that 
macro-like features has consequences that go beyond the compiler 
internals.
