[Gambas-user] Make String class friendlier

[Martin]

ok I understand.

So, if I want to extend the class String as Chain, for example, I use 
the instruction "Inherits String" but then when I create a Variable I 
must define it like "As New Chain" but String is just defined like "As 
String".

How I can give to the Chain.class the same behavior than String.class ?

Regards.

Martín.
