[Octave-bug-tracker] [bug #35157] Naive users baffled by "complex scalar type invalid as index value"

[Jordi Gutiérrez Hermoso]

Follow-up Comment #9, bug #35157 (project octave):

I don't see a reason to not provide a more specific error message if it's
something that is already being checked for.

Also, given the frequency with which i and j are chosen as index variable, I
think a(i) is provoking an error far more frequently than a(e) is.

Furthermore, the reason you don't see i and j as variables is because by
default they're not. They're in fact functions, and when you do i = 1, you're
shadowing function.  You can do i(2,5) with i's default value, for example, to
get a matrix full of i.
