       "Dispatch" adds another parser type to "Builder" permitting dispatch of parsing according to group names.

       Your group parser can also be a Dispatch parser. Thus you could potentially end  up  with  an  infinitely
       recursive parser.

       The     source     code     repository     for     DateTime-Format-Builder     can     be     found    at
       <https://github.com/houseabsolute/DateTime-Format-Builder>.

       "Dispatch" has just one key: "Dispatch". The value should be a reference to a subroutine that returns one
       of:

       •   "undef", meaning no groups could be found.

       •   An empty list, meaning no groups could be found.

       •   A single string, meaning: use this group

       •   A list of strings, meaning: use these groups in this order.

       Groups  are  specified  much  like  the  example in the SYNOPSIS. They follow the same format as when you
       specify them for methods.

       Bugs may be submitted at <https://github.com/houseabsolute/DateTime-Format-Builder/issues>.

       I am also usually active on IRC as 'autarch' on "irc://irc.perl.org".
