Variable e not usable for local-variable
The program mentioned in the other thread needed some local variables, as I am lazy I usually take short names and came up with e, as it should hold the result of euler(n), the editor refused to take it. So I used the cas to find out that e cannot be taken as a variable at all although I think to have read that all small letters are available. That is not very serious but can be changed if the system used another symbol, perhaps a fat printed e, for 2.718..., just like it does with i.
Maybe more meaningful error messages, especially in cas-programs where no debugger is available would be helpful, too. Errors like this take more time to find than writing the whole program.
