[marmarek]

None of the upstream scripts in there have constructs like this, and documentation doesn't recommend it either. Does this PR fixes some specific issue?

[DemiMarie]

No, this PR does not fix any specific issue. There was either a comment or a past commit message mentioning that variable scope was unclear, and this does fix that. The purpose is to prevent future changes from shadowing or clobbering some critical variable and introducing a bug that would be extremely hard to track down.

[marmarek]

Plasma people said each script gets isolated scope, so this is not needed.

[DemiMarie]

That is great! Do you have a link to the discussion @marmarek?

A question on the plasma matrix channel, I believe you are there too.
