when doesn't support expression, will it support in the future?

argo 3.1 supports Expression, see https://argoproj.github.io/argo-workflows/variables/#expression
but when doesn't support it, see below image, will you support it in the near future? It is useful in our cases

@liujiong1982 workarounds: 1) see if any of the govaluate comparators fit your use case or 2) calculate a value in a param using expressions and then use that param in the when expression.

I think there is an issues to add a new type of expression syntax for when.

[liujiong1982]

is there any plan for this issue to be resolved in 3.3 release?

[alexec]

No. Sorry.

When cannot be changed. Instead, we will replace it.

Per #7576, when actually did support expr expressions. And #9761 made that better supported (and removed the error message).

Re: whenExpression, see #7831
