Right, it's the same problem. Aliases are expanded early on, during
input, and so you can't use an alias within the same chunk of shell code
as where it's defined. This isn't going to change; you need to find a
workaround. The standard approach is to use functions in such chunks of
code. Aliases tend to be regarded as largely an interactive feature.
This ought to be documented somewhere, if it isn't.
