Line 1,278:
# The numbers between 2 and the square root of the input number are checked for even division.
# If the incremental number divides evenly into the input number, both the incremental number and the quotient are added to the list of factors.
Note that this implementation is tail-recursive and uses tricks of unification to "magically" pull the "L" variable seemingly out of thin air.
