If the intent of assert is only about sanity checks, then this would not be
unreasonable. C# has done similar <
https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.debug.assert?view=netframework-4.7.2
>.
If this is treated as a foot in the door for Code Contracts, then extending
debugger is inappropriate as the intentions are different.
The latter subsumes the former, but is probably a bridge too far for
ECMAScript at this stage. I would practically look for:
import {assert} from ''std:contracts"
along with comparable behavior to: <
