Description:
Prior to this change, the static
merge
behaved in a manner that was contrary to its types: it treated a single array as an array of sources. The staticconcat
did not do this, so changing aconcat
to amerge
or vice versa would effect wildly different behaviour if a single array was passed.This PR adds a failing test and removes the call to
argsOrArgArray
- which did the sniffing and unpacking.Regarding v7, there are a bunch of inconsistencies between
concat
,merge
,race
,combineLatest
,forkJoin
andzip
, but most can be addressed through the application of deprecations. This change, however, addresses an inconsistency in the implementation.Related issue (if exists): Nope
