Get or Set Variant attribute should not be polymorphic

[TCPlomp]

The Get and Set Variant attribute functions are polymorphic on the 'variant' input terminal.

Why?

What do you expect of the following code:

I think allowing this is a bad technique in a 'early typed' language like LabVIEW.

Or am I missing something?

Wel Set might be polymorphic.

But Get?

The terminal is NOT polymorphic.  And it is behaving exactly correctly.

This node takes a variant as an input. You wired something not a variant, so you get a coercion dot. LabVIEW will happily create a variant for you from the given data. It does that for any terminal that is variant type.

(Note: If the node were polymorphic, there wouldn't be a coercion dot because the node would be converting over to whatever version of itself accepts a boolean.)

Point taken!

this idea can be rejected.
