The using a string as a number thing was because I was testing what warnings were given and set a variable to 1 (numeric), concanated it with "1" with the . operand and then added a numeric number 1 to it, without getting any warnings about it.

This seems reasonable to me. Just assume that any time you do math with strings, or string operations with numbers that perl silently handles the type conversions required. So the below

>perl -e "print 1 . '1' + '.01'"
11.01

can be implictily read as

>perl -e "print str2num(num2str(1) . '1') + str2num('.01')"
[download]

but is much less confusing.

Dont knock it, eventually youll wonder why it isnt this easy in all of the other languages...

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
