Re: syntax error checking on object methods

I don't think anything like this exists, but it certainly sounds useful to me. It also sounds really, really hard to write! Consider this code:

   my $obj = some_func($some_arg);
   $obj->method();

It won't be easy to figure out what class to inspect for method(). The class of $obj may depend on $some_arg, which itself might come from some obscure source. Since Perl is a late-binding language intuiting the class for any given variable in the general case is going to be very hard.

Not to mention cases where the method name itself is dynamically computed at runtime. `my $method = $phase_of_moon eq 'waxing' ? "discombobulate" : "vreemflitzel"; $obj->$method( $price_of_tea_in_china );` [download]	[reply] [d/l]

I'd have missed both cases yes, so it's good I asked and I appreciate your answers. Maybe a full syntax checker on this is too much to desire, but a simple one that takes into account common cases where objects and methods are easily recognizable might not be that hard. In the long run a full syntax checker (if even possible) sounds like a good thing to have to me.	[reply]
