type pos = Fmlib.Character_parser.Position.ttype type_in_context = int list * Alba_core.Term.typ * Alba_core.Gamma.tA build context consists of a context with holes and a stack of to be constructed terms.
There is always a next to be constructed term. The term is either in a function position or an argument position.
val count : t -> intval count_base : t -> intval count_entries : t -> intval count_bounds : t -> intval required_type_in_context : t -> type_in_contextval make : Alba_core.Gamma.t -> tmake gamma
Make a build context based on gamma. Push 2 holes onto the context to get
Gamma, E: Any(2), e: E
The next to be constructed term points to e.
val final :
t ->

Stdlib.resultval base_candidate : range -> int -> Alba_core.Term.t -> int -> t -> t optionbase_candidate range variant term nargs bc
Receive the term term as a candidate for the next to be constructed term. The candidate is from the base context and in applied to nargs arguments.
Base candidates are either

t ->
tAdd a bound variable based on the last argument type and push a placeholder for the next argument type or the result type. I.e. expect the next argument type or the result type.
