Assigning Perl code snippet to a variable

perlpal has asked for the wisdom of the Perl Monks concerning the following question:

Hi Perl Monks,

Recently i came across code which looks like this

my $code = << 'ET';

{

  ---   Some lines of code ---
}

ET

test($code);
[download]

From what i can make out is the variable $code holds the code snippet terminating at ET. Am i correct ?

What is the use case/advantage of this implementation ?

Thanks in advance.

The Advantages of the here string is we can write a set of instruction or a function with in this here string. then we can give this to eval. here-doc/here-string allows us to print multi-line without worrying about the quotes and escaping that come with the standard method of the defining string. --sugumar--	[reply]
