The compiler toolkit does a lot of concatenation in order to generate
the PIR that ultimately gets compiled.  

The POST compiler converts each POST::Op node into the appropriate
PIR statement (a string), and concatenates these strings together
to produce the final PIR output.  So I suspect it's worth looking into.
