We've had this at Weka for a long time. It is an escape hatch in case very very deep template instantiation leads to stack exhaustion in the recursive needsCodegen function.

Is this hack still required at Weka? The needsCodegen() stack pressure should have been improved significantly for a while now, in dlang/dmd#14787.

I'll check whether it is needed with newer compilers (weka is currently still at 1.30)
