/**

\brief Given the context (n_1 : T_1 [:= V_1]) ... (n_k : T_k [:= V_k]) and expression e into,
|
||
|
|
return the "meaningless" lambda expression:
|
||
|
|
|
||
|
|
(lambda (n_1 : (foo T_1 V_1)) ... (lambda (n_k : (foo T_k V_k)) e))
|
||
|
|
|
||
|
|
The constant "foo" is irrelevant, it is just used as a marker.
|
||
|
|
It is used to "glue" T_i and V_i.
|
||
|
|
|
||
|
|
This little hack allows us to use the machinery for instantiating
|
||
|
|
lambdas with contexts.
|
||
|
|
|
||
|
|
\remark If a context entry (n_i : T_i [:= V_i]) does not have a
|
||
|
|
value V_i, then we just use (foo T_i).
