I was working with a long array recently and noticed that when I went to print out the entire array, that a regular
print statement doesn't force the array into scalar context but when concatenating it within a print statement, the array gets forced into scalar context thus giving me the number of elements in the array. Is this intentional? If so (which it must be), is there a way to "cast"
@x to be an array and not be forced into scalar context when its being concatenated? (Assuming that is what is actually going on). Thanks.
use strict;
use warnings;
my @x;
push @x, "this";
push @x, "that";
print "This is \@x:\n";
print @x;
print "\n\nThis is \@x\\n:\n";
print @x ."\n";
__OUTPUT__
This is @x:
thisthat
This is @x\n:
