Remove static properties from helpers

[Andarist]

Static properties used like this at the top-level are a common tree-shaking / dead code elimination deopt (because they affect other top-level statements) so ideally, this pattern should be avoided as much as possible.

This is the last PR from me today - I'd like to see how those play out first, but I have more changes planned.
