Single quotes are also a good way to delay $ expansion. In fact, using single quotes a lot and first prevents lots of surprises. In severe cases of quote and $ confusion, you can go to:
How would I combine something like:

ppi::token::quote
PPI::Token::Quote(3) User Contributed Perl Documentation PPI::Token::Quote(3)NAME
PPI::Token::Quote - String quote abstract base class
INHERITANCE
PPI::Token::Quote
isa PPI::Token
isa PPI::Element
DESCRIPTION
The "PPI::Token::Quote" class is never instantiated, and simply provides a common abstract base class for the four quote classes. In PPI,
a "quote" is limited to only the quote-like things that themselves directly represent a string. (although this includes double quotes with
interpolated elements inside them).
The subclasses of "PPI::Token::Quote" are:
'' - PPI::Token::Quote::Single
"q{}" - PPI::Token::Quote::Literal
"" - PPI::Token::Quote::Double
"qq{}" - PPI::Token::Quote::Interpolate
The names are hopefully obvious enough not to have to explain what each class is here. See their respective pages for more details.
Please note that although the here-doc does represent a literal string, it is such a nasty piece of work that in PPI it is given the honor
of its own token class (PPI::Token::HereDoc).
METHODS
string
The "string" method is provided by all four ::Quote classes. It won't get you the actual literal Perl value, but it will strip off the
wrapping of the quotes.
# The following all return foo from the ->string method
'foo'
"foo"
q{foo}
qq <foo>
literal
The "literal" method is provided by ::Quote:Literal and ::Quote::Single. This returns the value of the string as Perl sees it: without the
quote marks and with "\" and "'" resolved to "" and "'".
The "literal" method is not implemented by ::Quote::Double or ::Quote::Interpolate yet.
