The "try" is not necessarily for Perl's sake.  It's for the
programmer's sake.  It says, watch out, some sort of non-local
flow control may be going on here.  It signals intent to deal
with action at a distance (unwinding semantics).

I don't think we should obfuscate classic try/throw/catch/finally
from the ground up.  Humans have to read this code too.  When I'm
using non-local flow control to implement error handling, I very
much want the try, catch, and finally keywords to stand out from
non-unwinding-semantics control structures, so I have some chance
of getting the logic right, every time.
