Bash alias name from a variable

Is there a way to make a bash alias (or function) with its name coming from a variable?

For instance, is it possible to do something along these lines:

create_alias_with_name() {
  alias $1="echo a custom alias"
}

Or something along these lines:

create_func_with_name() {
  $1() {
    "echo inside a function with a variable name"
  }
}

In other words, I would prefer to have some kind of function "factory" that can register functions for me. Is this possible or beyond the capabilities of Bash?

just in case, one may use a variable both as a part of the alias name and as a part of the alias command:

alias foo${var1}="bar${var2}"

Did you even try it? Your first example works fine.

You can make the second work by adding an eval:

create_func_with_name() {
  eval "$1() {
    echo inside a function with a variable name
  }"
}
