map(p) affects any Array

[GoogleCodeExporter]

What steps will reproduce the problem?
looping through "associative" arrays

What is the expected output? What do you see instead?
add map(p) function to arrays only in GEX namespace?

sample script lines:
var associativeArray = new Array();
associativeArray["key"] = "value"; 
for (i in associativeArray)
{
...
}
one of the objects is "map", which was not added to array

The common way of dealing with this (which has become standard Javascript 
practice) is by only using Objects as associative arrays, not Arrays. There are 
several reasons for this, not least of which is the behavior of for...in loops. 
See, for instance, the warning at:

n_4

With that said, adding functions to Array.prototype directly is also 
suboptimal, and map should be moved to a separate function.
