When calling methods on com objects in vbscript (ugh! pain ouch ouch
ouch!) the overlaoded methods were accessed by a _number.

Lets say it's the Vacuum object (the object that makes windows suck).
In overloadable languages you can pass a Soul, an Idea, or Creativity
into the Vacuum's suck method.  The order they are defined in is
important because that's the order (as far as I was able to figure
out) that they are indexed in.
To use Vacuum to suck a soul it would be
myVaccum.suck_1(someonesSoul)
an idea would be
myVaccum.suck_2(goodIdeasAboutGuis)

But that was just in vbscript.
