The fact that not too many people has tried it is a symptom that people
don't like it too much.

I don't think we will need to decide between them. Maybe you can provide two
alternative syntax: one general that allows to declare functions with
contracts, concepts, named parameters, local functions ... and more
restrictive that can be used just to define simple local functions without
adornments. I really think with this approach your library will have much
more chances to be accepted and once your library accepted people would have
the possibility to choose between both alternatives.

I need to recognize that I will never tried it, but only crazy people
explores crazy domains showing that there is no limits to the innovation
(The first exception library was done using macros and now we have them on
Thanks for the hard work you are doing,
