Topic: [isabelle] adhoc_overloading Monad_Syntax.bind

I have problems combining adhoc_overloading Monad_Syntax.bind with
abbreviations. In the context of HOL-Probability:

adhoc_overloading Monad_Syntax.bind bind_pmf

abbreviation "f x y == (bind_pmf x (return_pmf o Pair y))"
term "f a b"

The output of the "term" command is the ugly rhs of the abbreviation (with infix

=). How can I phrase the abbreviation to make it work? Maybe with the help of
some translation?

Thanks a lot for quick answers!

Hi Tobias,

AFAIK the situation has not changed since August 2015:

So there's no way to reliably use adhoc_overlaoding with abbreviations.

That is correct. The whole issue is on my radar, but after the last
attempt (together with Florian) to improve the situation I never really
came around to look at it again.

Anyway, the help of somebody who is more proficient in Isabelle
internals would be highly appreciated.

cheers

Thank you for the link. It mentions [[show_variants]] which would solve some of
my problems. Can that be used locally in a term antiquotation? This does not
work @{term [show_variants] ...}

Try this:

setup ‹
Thy_Output.add_option @{binding show_variants}
(Config.put Adhoc_Overloading.show_variants o Thy_Output.boolean)›

I have that also on my radar. Maybe we get a chance to discuss it together
soon.
