Description Asumu Takikawa 2023-11-10 12:47:11 PST 
In the Wasm GC proposal, restrictions on `global.get` in constant expressions are relaxed. In particular, `global.get` may refer to previous globals when used in global initializers.

In tables, only imported globals can be used. In data and element segments, any valid global is fine.
