Hi

> Also, I don't understand what you mean by thinking of something "more elaborate"

well for instance, you won't catch all possible syntax errors:

lanx:/tmp$ cat tst.pl 
}; $hash = {
 
lanx:/tmp$ perl -c /tmp/tst.pl
Unmatched right curly bracket at /tmp/tst.pl line 1, at end of line
syntax error at /tmp/tst.pl line 1, near "}"
Missing right curly or square bracket at /tmp/tst.pl line 1, at end of
+ line
syntax error at /tmp/tst.pl line 1, at EOF
/tmp/tst.pl had compilation errors.
 
lanx:/tmp$ perl
$code = '}; $hash = {';                             
eval "sub { $code } ";       
print $@;
__END__
 
lanx:/tmp$ perl
$code = '}; $hash = ';
eval "sub { $code } ";       
print $@;
__END__
Unmatched right curly bracket at (eval 1) line 1, at end of line
syntax error at (eval 1) line 1, at EOF
