Just curious, why the check is implemented this way?
At least in the IL code something else seems to be analyzed.

Seemed like the easiest way to do it here. I'm definitely open to other suggestions. Maybe we should add IsFShartStructTycon. Or maybe just use IsFSharpStructOrEnumTycon because enum will never reach this place.

Leaving it up to you, just voting for consistent approach if applicable

I don't think we can do it like in ILTypeDef, but I did find another way which might be better.

So far it works for records and anonymous records.
Would like to get it to work for regular structs too but they seem to use a different mechanism for generating their getters.The following case is not covered, because that would require analyzing user supplied getter code for side-effects.
It does work for when the getter is auto-generated:
