     Type:  Feature Requests         |      Status:  new        
Milestone:  Boost 1.38.0             |   Component:  regex      
  Version:  Boost 1.36.0             |    Severity:  Problem    
 Keywords:                           |  
-------------------------------------+--------------------------------------
 The format string has the following syntax:
 (?ddexpression1:expression2), which limits the number of subexpressions
 that can be matched and replaced.

 If a regular expression contains more than 99 subexpressions that need to
 be matched and replaced (if matched), then it cannot be currently handled
 with the boost::regex_replace function because the format string cannot
 refer to a subexpression with an index greater than 99.

 Is this current limitation necessary?  If so, why?
