I share the point made by Lukas. Symbolvalue:value: is very obscure.
If we introduce Symbolvalue:value:, why not
Symbolvalue:value:value: and so on?

Maybe an alternative would be to use Helvetia to write blocks in shorthand.
Currently, writing the whole [:each | each abs] is a bit of a pain, so
the much shorter #abs is nice. But what if there was [… abs], the
ellipsis meaning it or the argument, duh ?
Several instances of … could be used in
I would be in favor of having value: value: on symbol and get rid of
value on Object
Because this is really cool to write #( 1 2 3) collect: #abs

Given that in Pharo we have Symbolvalue:, are there any reasons not
to have also
Symbolvalue: anObject value: anotherObject
^ anObject perform: self with: anotherObject
While Symbol#value: is at the border of being readable,
Symbol#value:value: is even worse. It is not immediately
do you have a scenario for it?
And I agree with lukas about value on Object

value from Object and value: from Symbol are different
with value: on Symbol you can do
self collect: #abs

My reasons for Symbolvalue: and similar selectors are as follows.
A Symbol is already used for several things, like a key in an identity
dictionary. But it is also used for parameterizing a mapping to
self collect: #abs
Yes, that looks cool.
However it is difficult to understand what it does for #(-2 3 4)
- Does it collect the literal #abs for all the values of the collection?
-- #(abs abs abs)
- Does it collect the values of performing #abs on the collection?
-- #(2 3 4)
