functionBody -- get the body of a function

Description

The body of f is essentially just the source code of f, with no frames providing bindings for the local variables in scopes enclosing the scope of f. Function bodies cannot act as functions, but they can be tested for equality (===), and they can be used as keys in hash tables.

i1 : f = a -> b -> a+b+a*b

o1 = f

o1 : FunctionClosure

i2 : functionBody f 1

o2 = FunctionBody[currentString:1:14-1:21]

o2 : FunctionBody

i3 : f 1 === f 2

o3 = false

i4 : functionBody f 1 === functionBody f 2

o4 = true
