left operand of the Elvis operator has to be a variable or a function

Description

This code runs without error on Adobe CF but fails on Lucee:

Error:

Even if it's just an example, elvis should accept any valid CFML expression on the left hand side.

This should probs be a bug rather than an “incompatibility”, yeah? Its implementation is - objectively - broken, right?

I just ran into this. This is reproduced from Slack:

 

Next one. This seems a bit contrived, but it's a distillation down from a more complicated & not-contrived situation.

The left operand should just be any expression that can evaluate to a boolean. It shouldn't matter if it's function call or a variable. It boggles my mind that there is code somewhere in Lucee that is written this way! Reminder:

However that error message is ballocks anyhow, as demonstrated here:

Sigh.

I've checked this ticket & also confirmed the issue reproduced on lucee while we didn't put any value in the left operand of this operator. It throws an error "left operand of the Elvis operator has to be a variable or a function call". Micha will confirm about this issue.
