You have to read between the lines a little bit, but the last large block of text in the `EXPORTS` section explains why calling `isa` as a function can give you the wrong results. The same reasoning applies to calling `can` as a function.	[reply] [d/l] [select]

> You have to read between the lines a little bit What about the WARNINGS part? `NOTE: can directly uses Perl's internal code for method lookup, and isa uses a very similar method and cache-ing strategy. This may cause strange effects if the Perl code dynamically changes @ISA in any package.` Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

you should know, you're the expert on.... everything. but more to the point, the answer is in tfm. guess you can't be bothered. or may we assume that this is another case of you making ignorant assertions pretending to be a question?	[reply]
