Dear Sergio, To assist in studying your patch would you be able to clarify your interaction with upstream.
I noticed that in Dec. 2010 you submitted a similar patch of languages.scm to upstream via the festlang-talk mailing list. Would you be able to clarify if this was received favourably and is intended to be included in a later upstream version or not. I was unable to find any reply on festlang-talk to your posted patch from Alan Black or Nickolay Smyrev on whether they lliked this new feature you have provided. with the very best of regards, Peter
