"To make it convenient to have a long string which uses regexp operators, a special syntax is provided. If a substring begins with " { $snippet "\\Q" } " then everything until " { $snippet "\\E" } " is quoted (escaped). For example, " { $snippet "R/ \\Qfoo\\bar|baz()\\E/" } " matches exactly the string " { $snippet "\"foo\\bar|baz()\"" } "."
