[jira] [Commented] (JEXL-175) java.util.regex.Pattern creation operator

["Henri Biestro (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JEXL-175?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14706765#comment-14706765 ] 

Henri Biestro commented on JEXL-175:
------------------------------------

Adding a new syntax for regexp adds lots of weight/complication when using a 'string'-based version is lighter and carries the same expressiveness power. In fact, the 'contains' operators ( ~= and ~!) already uses regexps under the hood when needed.
In general, the preferred way to add new feature is to use namespace/functors or overloading operators, not adding new syntax.

> The string inside slashes should not require to escape backslashes and quotes as in common string literals, so that regex would be more readable
