Hi all,
consider the following boiled down example, where I try to interpret a
locale while leaving some (all) parameters unspecified.
locale foo = fixes x::nat begin
definition "c = x + x"
end
interpretation foo .
*** Illegal free variable(s) in term: x
in constant abbreviation "c"
Why do I get this error message, and can I somehow work around it?
I would have expected an abbreviation of the form "c x == foo.c x" to be
declared.
In my concrete use-case, the locales have no assumptions, and I have to
instantiate some parameters.

Hi Peter,
The command interpretation used to accept omitted variables. Over the past years, it has
become a bit stricter about that. Now, you can declare free parameters in a for clause.
Here's an example:
interpretation foo x for x .
Best,
Andreas
