CWG2366 introduced the term "initialization full-expression" but never defined it. What exactly are we talking about here? The spec never actually defines what an initialization is or what it consists of from a grammar stand-point either, so no clues there.

We've used the following related wording elsewhere:

• the full-expression of the initialization
• the part of the full-expression that performs the initialization
• any full-expression in its /initializer/

If we can't come up with a definition editorially, can we reword the text to use one of the forms above so that we're not introducing a new term?
