Flex Builder 2 doesn error check .as...

When I make new flex project (basic project) and then make
new ActionScript class or file, I can type ANYTHING in and when I
save, Flex Builder doesn't report any error! Only when I try to run
application it reports an error. This doesn't happen inside of
script blocks in mxml files.



It is totally unacceptable!

Is it possible to change this?
