A fine-grain control of inlining at functor application via priority levels
As said in CHANGES:
<<
The inlining done during application of functors can now be controlled
more precisely. In addition to the "!F G" syntax preventing any inlining,
we can now use a priority level to select parameters to inline :
"<30>F G" means "only inline in F the parameters whose levels are <= 30".
The level of a parameter can be fixed by "Parameter Inline(30) foo".
When levels aren't given, the default value is 100. One can also use
the flag "Set Inline Level ..." to set a level.
>>
Nota : the syntax "Parameter Inline(30) foo" is equivalent to
"Set Inline Level 30. Parameter Inline foo.",
and "Include <30>F G" is equivalent to "Set Inline Level 30. Include F G."
For instance, in ZBinary, eq is @Logic.eq and should rather be inlined,
while in BigZ, eq is (fun x y => [x]=[y]) and should rather not be inlined.
We could achieve this behavior by setting a level such as 30 to the
parameter eq, and then tweaking the current level when applying functors.
This idea of levels might be too restrictive, we'll see, but at least
the implementation of this change was quite simple. There might be
situation where parameters cannot be linearly ordered according to their
"inlinablility". For these cases, we would need to mention names to inline
or not at a functor application, and this is a bit more tricky
(and might be a pain to use if there are many names).
No documentation for the moment, since this feature is experimental
and might still evolve.
