Now all regex functions use ScriptRule.

The *_rule functions can now be considered deprecated
Documented this by removing mentions of the rule functions, except for a mention of backwards compatibility.

-> match_rule(match:regular expression)(some_string)
 
 Does a string match the given [[type:regex|regular expression]]?
 
-This function is available in [[script:rule form]].
-When the match is performed many times the rule form is more efficient, because the regular expression is only compiled once.
+When the match is performed many times with the same regular expression it is more efficient to declare that as a default argument:
+> my_match := match@(match: "something")
+> my_match("input") # called many times
+This way the regular expression is only compiled once.
