If you never use ell's, then anything that looks like it might be an ell is actually a one. The fact that these two characters look similar doesn't mean you can't use either of them; rather, you have to pick which one you'll allow yourself to use, and don't use the other one. Note that I only forgo using the token "l", not the character. So with my convetion, it's fine to call a variable "lock", or to use required names like the keyword "yield" or the "__call__" class method.
