mk_anylet : (term * term) list * term -> term
STRUCTURE
pairSyntax
SYNOPSIS
Constructs arbitrary let terms.
DESCRIPTION
The invocation mk_anylet ([(a1,b1),...,(an,bn)],N) returns a term of the form `LET P Q`, which will prettyprint as let a1 = b1 and ... and an = bn in N. The internal representation is equal to 
    LET (...(LET (\an ...\a1. N) bn) ...) b1
Each ai can be a varstruct (a single variable or a tuple of variables), or a function variable applied to a sequence of varstructs. In the usual case, only a single binding is made, i.e., mk_anylet ([(a,b)],N), and the result is equal to LET (\a. N) b.
FAILURE
Fails if the type of any ai is not equal to the type of the corresponding bi.
EXAMPLE
- strip_comb (mk_anylet ([(Term`x`, Term`M`)], Term`N x`));
> val it = (`LET`, [`\x. N x`, `M`]) : term * term list

- mk_anylet ([(``f (x:'a,y:'b):'c``, ``M:'c``), (``g (z:'c) :'d``, ``N:'d``)],
             ``g (f (a:'a,b:'b):'c):'d`);
> val it = ``let f (x,y) = M and g z = N in g (f (a,b))`` : term
USES
Programming that involves manipulation of term syntax.
