This PR enables
Set,Clear, andClearCollectto be used inForAll. This has been a long-time customer request that we told PPCC 2024 audiences that we would do.These functions have been disallowed until now with the hope that we may someday parallelize
ForAll. However, this was attempted in Canvas and customers had found other ways to take a dependency on the order of evaluation. We are officially giving up on this notion -ForAllwill from this point forward always be sequential (as it always has been).We will also introduce a new
Mapfunction that does not support side effects in the lambda and can be parallelized.This is not a breaking change. This previously generated an error, but no longer.
