<div dir="ltr">Hi all,<div> interesting thread!!</div><div> Class name prefix are not nice but it is very easily to get used to them. When you got use to them when you read something like WAHtmlCanvas, your mind disregards the WA and focus on HtmlCanvas. Prefix do not look nice, but they solve the problem of name clashing in a simple way and without adding anything special... but namespaces look as a better "engineering" solution :-)</div><div> Many details have to be take care when implementing namespaces, it is not that simple. The implementation I liked about this was Geman Leiva's one, showed at ESUG 2010.

Without backticks, we'd need to add packages as globals, so
they can be <br>
resolved at runtime. With the backticks we can avoid that,
because we <br>
can give the Compiler the context to resolve package names
if in a <br>
required package, just like class names, at compile time.<br>

changing Class>>bindingOf:. Currently it first looks
in class var names and SharedPools calling

Smalltalk bindingOf:. I added a packageBindingOf: after

to resolve the binding within the package. We can put
required packages here and they will look like globals,

You are right! Yes, the backticks are optional. There is still the
message send to get the class. So there is some performance penalty,
and some users in critical code might still prefer to use them, so
the literal is the class and not the module. But it is a small
detail.<br>
