Not sure if my last post made it out so sorry if this get's duplicated..
I wrote a function which returns a closure:
sub create_randomness
{ #($direction, $granularity, $sort)
my ($direction, $granularity, $sort)=@_;
sub
{
my @X=();
for(@{$DATA[$direction][$granularity]})
{
push(@X,$_->[$sort]);
}
('hist',[[@X]])
}
}
anyway. When I try to debug a program with these closures, I get the following
Undefined subroutine &main::__ANON__ called at /usr/local/lib/perl5/perl5db.pl
line 536, <DATA> line 60418.
however when the program is run it works just fine..
Is there a way around this problem w/o droping the closures?
the way I used the above function was I created an array
of arrays
each sub array has a reference to a function (returned from the above
function)) and other data to go with the function...
I had planned to use closures in some code in the future but
not being able to use the debugger could prove to be a little high of
a price to pay...
Any ideas?
