Hello Monks,
I have not written any perl in ages and I was recently asked to reverse engineer several scripts at work. Everything was going well until I got to this.
if ( exists $nums{$stuff[0]} ){...}
My question is what is $nums{$stuff[0]} ? I know that I am looking at a key ($stuff) of a hash (%nums). The 0 completely throws me off. Does the zero imply that there is more than one $stuff ? Is 0 the first of a series of keys with the same name? Any help would be appreciated.
