Description:
In mysqltest,

--die Error: $my_error

gives:

mysqltest: At line 100: Error: $my_error

I think it would be better it the $variable was expanded so that we could use it to add more information in the error message.

How to repeat:
Create a test that contains

let $var= something;
die Error: $var

...and see that the output is:

mysqltest: At line 2: Error: $var

instead of

mysqltest: At line 2: Error: something

Thank you for the feature request.

This is a special case of the newer Bug #46528, which I would prefer to make a general solution for rather than adding hacks for individual commands.
