Re^2: To Single Quote or to Double Quote

[Joost]

single quotes will escape all escape charater

Not completely:

print 'there\'s a \' quote here, there\'s a \\ backslash here';

Anyway, it works the other way around: single quotes interpret only a few escape sequences, double quotes have more (and they interpolate variables).

See the section on "Quote and Quote-like Operators" in perlop.
