[plt-scheme] transforming?

Some procedures only work during a syntax transformation
(e.g. `syntax-local-value' and `local-expand') and raise an exception
if they're called otherwise:

> (syntax-local-value #'foo)
syntax-local-value: not currently transforming

Is there a way to tell if you're currently transforming, other than
catching the exception?
