[ 2686538] Python inline code at left-hand side of the colon

[HolQue]

A lot of things can go wrong with Python inline code. The following examples, for instance, all cause different error messages. And each of the error messages is correct.

"<<[1, 2]>>" : 1
<<1 if True else 2>> : 1
${<<1 if True else 2>>} : "B"
${<<1 if ${A} else 2>>} : "B"
${A}[<<0 if True else 1>>] : 4

But in the examples above, all expressions with Python inline code are located on the left-hand side of the colon. And the question is: Do we have any valid use case for Python inline code on the left-hand side of the colon? I do not see one.

In my opinion the error handling for expressions on the left-hand side of the colon can be shortened by the following rule:

Python inline code on the left-hand side of the colon is generally not allowed.

All further details (e.g. not allowed within strings) are irrelevant and misleading in this case.

Hi @HolQue ,

"Python inline code on the left-hand side of the colon is generally not allowed."

This fit's to the philosophy for the moment no to allow dynamic key-names.

Thank you,
