Actually its very strait forward if we phrase those rules a bit differently:
* The qq operator is synonym to double quotes
* The q operator is synonym to single quotes
* Inside double quotes perl interpolates: variables and special sequences
("\n", "\"",
etc)
* Inside single quotes perl does not interpolates (e.g: a " is not
special inside single
quotes).
The only special sequences inside single quotes are:
* Backslash-single-quote: otherwise there was no way to insert single
quote
character into a single quoted string (no interpolation...)
* Backslash-backslash: otherwise you could not insert a backslash as the
last
character in the string (the previous rule would apply -- \' )
Enjoy,
