In many cases, several names are needed to invoke the same command.

It would be nice to have a way to specify an alias for a command, and have the alias mentioned in the help, without the need to define repeated entries in a command dictionary, and without the redefined function appearing several times in the help message.

For instance, doing this:

# 1.py
import clize

def foo():
    "Function foo"
    pass

def bar():
    "Function bar"
    pass


if __name__ == '__main__':
    clize.run(dict(foo=foo, bar=bar, foo2=foo))

produces

Usage: 1.py command [args...]

Commands:
  foo    Function foo
  bar    Function bar
  foo2   Function foo

The desired outcome (by whatever method is implemented) would be more like

Usage: 1.py command [args...]

Commands:
  foo    Function foo (alias: foo2)
  bar    Function bar
