[Glass] How replace in String works

[Dale Henrichs]

Bruno,

In GemStone, literal strings and array are created invariant. As you 
have discovered a copy of the string is not invariant, so if you are 
created literal strings  that you intend to modify then you should do 
the copy at creation time ...
