[Pharo-project] about consistency between hex implementations

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. Stef
