In addition to what other monks have said:

• Don't use mixed case style in variable and subroutine names. It is ugly and unreadable IMHO. Use all lowercase, and separate words with _ (underscore). However, if you're maintaining code, you may choose to stick with the existing convention. (s/doSomething/do_something/ - much better...)

• Use short, familiar names for short lived variables and long, descriptive names for long lived ones. Don't try to "compress" or "pack" many words or concepts into a cryptic, unspellable variable name. A few more keystrokes will save you many a headache two weeks later. Anyway, what does the "l" in $lResponce stand for?

  Besides, I think it should be the other way around: $response in the inner sub block, and $lxxxxx_response in the outer scope. (substitute lxxxxx with the answer to my previous question)
