Algorithm.foldl

Evaluates f(f(f(value, e1), e2),...en) using values from an enumerable.

value0

is the first argument for the inner function call.
The

enumerable

provides the second arguments to function calls, can be a Container, a Range, or a builtin-list.
The

callable

has the following stack notation:

( inputValue0 inputValue1 -- outputValue )

value1

is the resulting value.

Depends on the enumerable and the callable.
