Subject: [Bug c/111421] constexpr not working with array subscript
Date: Fri, 15 Sep 2023 17:21:03 +0000	[thread overview]
Message-ID: <bug-111421-4-NprMoHnfDa@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
The definition of constexpr in C2x is intentionally minimal, with 
potential for future expansion in subsequent standard revisions.  
Allowing array element accesses would run into needing an appropriate 
definition of exactly what cases are allowed and don't count as accessing 
the value of an object (presumably including requiring the array element 
index itself to be an integer constant expression within range for the 
array in question).
