Re: How to access directly an element of an array / list returned by a function?

Turn it not into an anonymous array, but an anonymous list, and you have the standard Perl idiom:

my $name = ( File::Spec->splitpath($path) )->[2];

update: must have been the caffeine level dropping too low .. .no need for '->' in list.

As Occam said: Entia non sunt multiplicanda praeter necessitatem.

That doesn't work with the dereferencing operator (->), since the return of File::Spec->splitpath is not a reference. This works: `my $name = ( File::Spec->splitpath($path) )[2];` [download] Steve	[reply] [d/l]

Your code used the [] markers around your function to create an anonymous array reference, with that the -> dereference was a correct, if scenic, choice. Tom's solution used () for precedence to help the parser understand that the list returned from the function is what needs slicing. Unfortunately he kept the -> which was incorrect.	[reply]
