The first fix is that after the yield return, we should move on to the next command The second fix is that if we find _any_ command, we should not move on to the 'Get-<command>' variant These changes mean that we do not run a pipeline (twice!) to find something that was a cache miss. In the pathological case of a script mmade up of only unique aliases, we would run 2 pipelines for each found alias.

There was a problem hiding this comment.
One minor suggestion but looks great otherwise. I will modify PR #1178 to not parallelize the AvoidAlias rule any more since with this improvement the rule is no longer the weakest link in the chain

PR Summary
The first fix is that after the yield return, we should move on to the next command
The second fix is that if we find any command, we should not move on to the 'Get-' variant.
These changes mean that we do not run a pipeline (twice!) to find something that was a cache miss. Previously in the pathological case of a script made up of only unique aliases, we would run 2 pipelines for each found alias. This fix avoids both of those pipeline invocations.
