SC2142: Function in the alias definition

[aeiplatform]

For bugs

• Rule Id: SC2142
• My shellcheck version: 0.7.0
• The rule's wiki page does not already cover this at Wiki
• I tried on shellcheck.net and verified that this is still a problem on the latest commit

Here's a snippet or screenshot that shows the problem:

#!/bin/sh
alias idc='idc() { echo "$@"; }; idc'
alias idk='i() { echo "$@"; }; i'

Here's what shellcheck currently says:

Line 2:
alias idc='idc() { echo "$@"; }; idc'
      ^-- SC2142: Aliases can't use positional parameters. Use a function.
 
Line 3:
alias idk='i() { echo "$@"; }; i'
      ^-- SC2142: Aliases can't use positional parameters. Use a function.

Here's what I wanted or expected to see:

Nothing. Function is used in the alias definition.

You can demonstrate this with a shorter anonymous function:

alias idc='() { echo "$@"; }'
