Workaround bug with rhai 0.19.8 #8

Closed schungx closed 3 years ago

schungx commented 3 years ago

There is a bug in 0.19.8 that is fixed in 0.19.9. That bug causes a syntax error when accessing properties within a closure.

0.19.9 does not build on WASM, however:

Arrrrrgggghhhhhh.... yes, no_std was broken in 0.19.9. No worries then...

Maybe you can switch stable to 0.19.7?

alvinhochun commented 3 years ago

Ok, I moved stable to use 0.19.7.
