Hi,
There exists already a method for that:
Symbol>>asClassInEnvironment:
But, what if we introduce:
Symbol>>asClassFrom: anObject
^ self asClassInEnvironment: anObject class environment
?
The problem is asClass unary.
All the tools should be parametrized by an environment.
This would allow us to still script and be dynamic.
Furthermore, as #asClass is meant to be mainly used for convenience, not
performance, I would also propose to make it lookup in thisContext and take the
environment from there. I know that his might sound like magic, but it would be
the default that we are looking for (to always lookup through the current
environment dynamically).
argh I will die....:)
No use of thisContext or only in the scripting package.
What do you think?
Cheers,
Doru

Just my 2 cents:
instead of
#name asClass
we have to use
self class environment at: #name.
Maybe instead of #at: we can have #classNamed:? Or something similar? Because
1) it’s not obvious that the method will give you a class, what if in the
future and environment can also have a mapping of something else like packages?

Hi guys
We got a meeting at ESUG with all the compiler guys and james from gemstone.
Our goal is to have a full tool suite that can be parametrized by environments
(so that
we can compile code in other space, or compile other code inside pharo).
I personnally started this effort one decade ago. Now the introduction
of #asClass and friend is simply destroying all our efforts. There was a
discussion
in the past but we are not listened.
We will
- packaged these extensions in a separate package
- add rules to ban the use of such method in Pharo
- fix all the use (again) to use the correct way to do it.
I can understand that for scripting this is easier but it cannot be at that
cost and impact.
I hope that we will understand but we have to do something else than
fixing code that breaks our effort.
