We have posted a new Fantom build.
This is mostly a much needed maintenance build.
But there are a few small language features...
You can now use once methods on a const class per proposal 2820. Note the caveats in the updated docs.
We've also made a subtle change in allowable function types. Previously you could only use This in a function type if the full function type was |This->Void| (for use in it-blocks method params). We've relaxed those rules to allow This to be used in any function parameter position, but only when the function type appears as a method parameter (which is covariantly safe).
Build 1.0.76 (10 May 2021)
Hooray! Thanks! :D
