It's a common "corruption" of C, based on the question:
"Shucks, it's a pointer to a function; what the heck else are ya gonna
do with the dang thing except dereference it, i.e. call what it points to?"
Technically, the explicit dereference is required, i.e. ((*action)())
Pcc-based implementation imply the dereference as necessary. I don't even know
if 4.[23] lint would complain about this one.
