The switch/case might be the result of initially basing the grammar on  
the C grammar. So presumably it should be removed.

In the Ruby grammar we have a list of functions that take regexp  
arguments to solve the division/regexp ambiguity -- something similar  
could be done for perl wrt the split case.
