Hi, The following code throws a "Undefined variable a1:" error:
let a1 = 1 | let b = [1,2,3] | echo b[a1:-1] When one puts a blank after a1, it's ok though: let a1 = 1 | let b = [1,2,3] | echo b[a1 : -1] Since "a1" is no valid scope and "a1:" is an illegal variable name, IMHO this code shouldn't be considered ambiguous. Regards, Thomas.
