Editing Delimiter (section)

====Escape character====
One method for avoiding delimiter collision is to use [[escape character]]s. From a language design standpoint, these are adequate, but they have drawbacks:

* text can be rendered unreadable when littered with numerous escape characters, a problem referred to as [[leaning toothpick syndrome]] (due to use of \ to escape / in [[Perl]] [[regular expression]]s, leading to sequences such as "\/\/");
* text becomes difficult to parse through regular expression
* they require a mechanism to "escape the escapes" when not intended as escape characters; and
* although easy to type, they can be cryptic to someone unfamiliar with the language.<ref name="Kahrel000">{{cite book
