Hello, wise Perl friends.

There ought to be a repository of common expressions and how they behave in each context / what their default context is. I know there are tons of vanilla examples found in tutorials everywhere (such as assigning an array to a scalar) but some slightly more sophisticated operations still trip me up.

For example:

m/.../     returns true or false in scalar context
m/.../g   give you a list of matches in list context
m/(...)/   can populate an array with whatever gets captured... (??)

while( )   i.e. inside parenthesis is evaluated in scalar context?
foreach( )   i.e. inside parenthesis is evaluated in list context?

[download]
<STDIN>   returns the next line of input in list context

In fact, I could be wrong on a lot of these but that's not my point. Is there a handy reference-like guide available anywhere that tells you how these expressions behave?
