2018-08-31prim notations backtrackable, their declarations now in two parts (API change)Pierre Letouzey
The first part (e.g. register_bignumeral_interpretation) deals only with the interp/uninterp closures. It should typically be done as a side effect during a syntax plugin loading. No prim notation are active yet after this phase. The second part (enable_prim_token_interpretation) activates the prim notation. It is now correctly talking to Summary and to the LibStack. To avoid "phantom" objects in libstack after a mere Require, this second part should be done inside a Mltop.declare_cache_obj The link between the two parts is a prim_token_uid (a string), which should be unique for each primitive notation. When this primitive notation is specific to a scope, the scope_name could be used as uid. Btw, the list of "patterns" for detecting when an uninterpreter should be considered is now restricted to a list of global_reference (inductive constructors, or injection functions such as IZR). The earlier API was accepting a glob_constr list, but was actually only working well for global_reference. A minimal compatibility is provided (declare_numeral_interpreter), but is discouraged, since it is known to store uncessary objects in the libstack.
