Description
Consider this rule:
An expression or conversion is potentially constant evaluated if it is:
- [...]
- an immediate subexpression of a braced-init-list
In the current standard, all formal definitions for immediate subexpressions are based on an expression, that is
basic.exec#intro.execution-3
The immediate subexpressions of an expression E are
- [...]
Informally, a braced-init-list is not an expression. How to determine what are the immediate subexpressions of a braced-init-list? There's no other rule specified for this conception. Does it refer to the immediate subexpressions of the constitute expressions of a braced-init-list?

Research direction
Start with basic.exec#intro.execution-3 and the cited rule for expressions or conversions that are potentially constant evaluated. Determine whether the standard defines immediate subexpressions for a braced-init-list or its constituent expressions; done means resolving the ambiguity in the draft wording.
