Beware that some delimiters have special meanings. e.g. m/$foo/i interpolates $foo whereas m'$foo'i does not.

Regular expressions are not the only delimiters that can be replaced with whatever. qq(), q(), qx() and qw() work similarly. For example, the following assigns a string consisting of a single space character to $foo:

my $foo = q q q;
