Panic when evaluating an expression that adds a number to an array

[tiymat]

Describe the bug:
Evaluating the following expression (or seemingly any of the same form, where a number is added to an array) causes a panic.
1 + %[1]

Expected behaviour:
An error should be printed without Murex crashing.

Screenshots:

Platform (please complete the following information):

• OS, output from uname -a if supported: 6.9.7-arch1-1
• Terminal Emulator: kitty 0.35.2
• Murex version, output from version --no-app-name: 6.1.8300

Additional context
Attempting to add a number to an object (e.g. 1 + %{"foo":"bar"}) is properly handled and returns an error without panicking.

I'm currently working on something that involves going through a lot of edge cases involving expressions, and filing a lot of (potentially low-priority) issues as I discover them. If it's preferable for me to wait until I'm done and create one larger issue containing all the sub-issues I've found please let me know!

Smaller tickets are easier to write tests against so the approach you've taken already is good.

Also want to add that I really appreciate all the testing and bug reporting you've done. It's fantastic work. Thank you!

Well, thanks for all you do to develop and maintain this great tool!

And it turns out that in light of ='s impending deprecation, I might not actually have many to report after all, as the ones I was thinking of were things like = behaving differently than other ways of writing expressions.

So for example the below one differs between = and just writing the expression, but just writing the expression and expr both give an error when evaluating it, so after = has been removed it won't be an issue anymore.
