	Traditional Unix regular expression syntax followed common conventions but often differed from tool to tool. The IEEE POSIX 1003.2 Basic Regular Expressions (BRE) standard (released alongside an alternative flavor called Extended Regular Expressions or ERE) was designed mostly for backward compatibility with the traditional (Simple Regular Expression) syntax but provided a common standard which has since been adopted as the default syntax of many Unix regular expression tools, though there is often some variation or additional features.<br>		Traditional Unix regular expression syntax followed common conventions but often differed from tool to tool.

	Perl has a more consistent and richer syntax than the POSIX basic (BRE) and extended (ERE) regular expression standards. An example of its consistency is that \ always escapes a non-alphanumeric character. Another example of functionality possible with Perl but not POSIX-compliant regular expressions is the concept of lazy quantification (see the next section).
