  Sat Jun 28 03:33:14 2014 perl [...] toby.ink - Ticket created
Subject: array->exists
I may have a go at implementing this myself later, but for now filing a ticket so I don't forget. It would be useful if arrays had an ->exists method like hashes do. my $arr = array(qw/ foo bar /, undef); $arr->exists(0); # true $arr->exists(1); # true $arr->exists(2); # true $arr->exists(3); # false because 3 > $#$arr I'm not sure what the ideal behaviour of $arr->exists(-1) would be.

I've pushed an 'array-exists' branch that adds exist() and defined() for array objects. Admittedly the nested ternary isn't pretty, but that seems pretty much in-keeping with the rest of Lowu... I think the negative integer behavior (see t/01_array/exists.t) should vaguely match what you might expect of perl, but it's also 4am and I'm drinking lemon shandy, so I'd appreciate a sanity check ;-)

Um. 'exists()', rather...
