Tetris project failure: ambiguous selector this.Reset

[nighca]

Summary

Opening and building the Tetris project from XBuilder fails with an ambiguous selector error.

Reproduction

1. Open https://x.qiniu.com/project/go-wyvern/Tetris
2. Trigger project build/run
3. Observe the build failure

Actual Result

The build fails with the following error:

failed to build: failed to load XGo source: BlockS.spx:3:8: ambiguous selector this.Reset

Expected Result

The project should build successfully, or the compiler should provide a deterministic resolution instead of reporting an ambiguous selector for this.Reset.

Project

https://x.qiniu.com/project/go-wyvern/Tetris

Notes

This was reported from the XBuilder side, but the failure appears to come from spx while loading the XGo source.
