Description:
This PR reverts the changes made to the
SchedulerLike
interface. As discussed in the core-team Slack channel - with @MichaelJamesParsons - the changes broke user-land schedulers. (Angular Zone-related schedulers are not uncommon.)Although the typing of the
SchedulerLike
interface in arguably incorrect, it might be best to leave it as-is and delay any changes to the scheduler infrastructure until version 8.The reversion has necessitated the liberal use of
as any
assertions, as all of the dispatch/work functions assume astate
that is notundefined
. This problem was hidden until thestrict
typescript option was enabled. I did try a few other approaches - including using a conditional type instead of theas any
assertion - but they didn't work out.Related issue: None
