[asterisk-users] Asterisk dialplan best practices syntax

[Tech Support]

Hey;
    Don't forget Perl. I'm not sure what everyone else calls it, but most
Perl programmers call it a "fat comma".

    From Chromatic's "Modern Perl" book: One of the simplest but most useful
examples of TIMTOWTDI in the design of Perl is the fat comma operator (=>),
which acts like a regular comma except that it automatically quotes
barewords used as its left operands. It also looks like an arrow, so it
leads from left to right and implies a stronger association between its
operands than the normal comma does.

You can see this in hash initializers:

my %dogs = (
    alpha => 'Rodney',
    clown => 'Lucky',
    puppy => 'Rosie',
);

Regards;
John V.

The only language I'm familiar with (I'm primarily a 'c' guy) that uses '=>'
is PHP. In PHP, '=>' is used with associative arrays.

I tend to think of a dialplan as a group of one dimensional linear arrays
with the name of the array being the context concatenated with the exten so
for me, a simple assignment makes sense.
