Like this:
define method = blabla{x}
define class Example where x = foo, bar = global blabla
call Example.bar > foo

You have to keep in mind that Google is about politics, and if you search like a dilettante, you won't find anything there.

I clarified and gave some examples
maybe like that
define method = blabla{x}
define class Example where x = foo
call blabla with contextOf Example > fooExample.x = baz // redefinition
call blabla with contextOf Example > baz
Delegation means that the called method or property is not in the environment of the object, but delegates it to its class or superclass, only the name is in the environment of the object

Method inheritance by delegation means, that when a method is called, it's realisation always looked up in the class(class is runtime object in this case)
And dynamic resolution will mean, in addition to this, that the resolution can be not only in the context of the lexical environment (dynamic scoping)
In this case, during compilation, it is impossible to make substitutions, inline, but even create a table of virtual methods

can you provide a reference to clarify your reasoning?
This is not reasoning, but a fact, you can find the "link" by request "inheritance by delegation" or read about the implementation of inheritance in languages like js, self, smalltalk or python

The very assumption that this can be confused looks as strange as if someone confused inheritance with composition. Here compilation means translation with optimization.

Maybe you mean composition
You are confusing categories here. It was about the implementation of inheritance. It can be implemented by delegation or copying. This is about the same difference as between the regular and virtual methods. And composition is a method, a template. And composition is not inheritance at all, it is surrogate
If name resolution occurs already at compile time, this means that we are dealing with a copy derived from the class. This situation is beneficial for compiler manufacturers. The analisys would be much more difficult if they don't know how it resolve in runtime

You can have your own opinion.
The general definition of delegation in programming is a call in the context of another object(implicity or explicity).
