Using `with` control structure yields "unknown token" error
When I make any use of the `with` control structure in a Dataiku formula in a Prepare recipe, I get an error message complaining that the variable name is an unknown token. For example, if I use the formula example from the documentation:
with("european union".split(" "), a, a.length())
Dataiku complains "Formula is invalid : it has some unknown tokens" and highlights both instances of the variable `a` in red.
What am I doing wrong? Thanks!

Is "a" the name of your column? My test column was called Folder. Works for my column when using v10.0.7.

Wait, you can only bind the expression to an existing column name...?
I'm not sure what the value of the construct is in that case.

No, but you copied pasted a formula using a sample column name. What exactly are you trying to achieve? Describe your requirement.
