Dumb question, but can the Emscripten version be detected so as to skip based on that version? I think there's prior art for this for various other platforms.

It almost certainly can be; but it will require the analog ofplatform.ios_ver()/platform.mac_ver() (et al) to expose the platform version identity. I imagineplatform.emscripten_ver() (orwasm_ver, if there's an opportunity to share with WASI) will eventually exist; but it doesn't yet.

We havesys._emscripten_info.emscripten_version. So we could add the following tosupport:

defis_emscripten_lt(ver):ifnotis_emscripten:returnFalsever_tuple=tuple(int(x)forxinver.split("."))returnsys._emscripten_info.emscripten_version<ver_tuple

and then putskipIf(is_emscripten_lt("4.0.1")).

We'll eventually want to surface the version in platform for consistency, rather than the semi-private name on_sys. I'd also suggest using a tuple, rather than parsing the string at runtime,

We could also consider making this a feature ofis_emscripten , so thatskipIf(is_emscripten()) is "skip any version" andskipIf(is_emscripten((4,0,1)) does an additional version check.
