Asumu Takikawa
The Wasm GC proposal adds several new instructions that are constant expressions and can appear in global initializers (https://github.com/WebAssembly/gc/blob/main/proposals/gc/MVP.md#constant-expressions).
The instructions are i31, struct, and array allocation, and extern.externalize/internalize.
The proposal also generalizes global.get use in constant expressions.
It would probably make sense to implement this along with extended const expressions: https://bugs.webkit.org/show_bug.cgi?id=252483
