Description:
This PR deprecates the
thisArg
signatures.Unfortunately, the deprecation of predicates that accept a
source
parameter isn't possible. When the non-deprecated signatures - i.e. those with predicates that do not acceptsource
parameters - are added, the inference breaks and calls that pass source-accepting predicates won't compile - for the dtslint tests - because the parameters are inferred asany
and implicitany
is disallowed. I can guess at what's happening internally - 'cause, normally, you would not have separate signatures - but the inference failure is still weird.The removal of the
source
parameters will have to be conveyed in documentation instead. Or left as a breaking change surprise.Related issue (if exists): #6143
