iter_head_constructor f lam
apply f
to only the first level of sub expressions of lam

Same as iter_head_constructor

subst update_env ?freshen_bound_variables s lt
applies a substitution s
to the lambda-term lt
.
Assumes that the image of the substitution is out of reach of the bound variables of the lambda-term (no capture).
update_env
is used to refresh the environment contained in debug events.
freshen_bound_variables
, which defaults to false
, freshens the bound variables within lt
.
A version of subst
specialized for the case where we're just renaming idents.
Bottom-up rewriting, applying the function on each node from the leaves to the root.
Rewrite each immediate sub-term with the function.

record. This is unlimited (max_int
) for bytecode, but limited (currently to 126) for native code.
