[Pharo-project] about consistency between hex implementations

[stephane ducasse]

Hi eliot

I was going over some changes and I noticed that in squeak

20 hex 
        16r41
$A hex
        '41'


in pharo we have 
        hex that always returns 16rXX

        $A hex '16r41'

        20 hex  '16r14'

Even if this is regular this is not really nice. In fact this ones should be 
fixed to return numbers and not strings.
I do not understand why hex should return a string. 

and in pharo 
        printStringHex the XX part only
        
$A printStringHex 
        '41' 

20 printStringHex 
        '14'

Here this is a string since the name says it.

In VW there is asHexString which is nice too.

So could we agree on that and get a system that is nicer and more consistent.
