Perl is a computer language that is very close to the natural language. It is a computer language that can be written as a prose.
It is because of this, today I have made the following mistakes, I spent an hour, I know that I am so crazy.
Just discovered.
This from a class, only one method
#! / usr / bin / perl -w
Use strict;
Use Data :: Dumper :: Simple;
SUB CRAZY
{
MY $ SELF = Shift;
Die "Rent NOT Paied: $!" Unless UndEf $ Self -> {Rent}; #here!
# .... do sth with $ self-> {rent}
} "If there is no rent, you will die" - how natural! But Undef is not a defense of defined, in fact, she is a way to make everything. Under the role of UNLESS, this sentence becomes nonsense.
