reporting syntax error

hi all.

i am in the process of writing a plugin.
i realize when i make a syntax error, nothing will be output and i have to check the apache log.

here is the question:
how can i change wp so that it will report syntax error to client?
like in normal php… if u do
<? invalid syntax’ (); ?>
the brwoser will tell u that u have made a syntax error.
how can i make wp behaves like regular php
