Brace eval is functionally equivalent to try/catch in Java or C++.
Don't fear it at all if you are just wrapping some code to catch
exceptions, there's no performance penalty.

String eval on the other hand IS quite slow, as perl has to recompile
that code string every time through.  It doesn't start another
interpreter per se, but it's slow.  There are certain times when you
need this, but exception handling isn't one of them.
