Hi all,

What is the syntax to use polymorphic variants with camlp4 ?

<:str_item< type a = A >> is ok, but <:str_item< type a = [ `A ] >>
doesn't work as expected...

While expanding quotation "str_item":
Parse error: '=' or '>' or '<' or [a_list] or [constructor_declaration]
  expected after '[' (in [type])
Uncaught exception: Pcaml.Qerror("str_item", 1, _)

When is the new version of camlp4/3.10 due ?
(this month, next month, next year) ?

thanks :)
p
