Macro assert_program_args_stderr_string_is_match_as_result 

macro_rules! assert_program_args_stderr_string_is_match_as_result {
    ($a_program:expr, $a_args:expr, $matcher:expr $(,)?) => { ... };
}

Assert a command (built with program and args) stderr into a string is a match to a regex.

Pseudocode:
(a_program + a_args ⇒ command ⇒ stderr ⇒ string) is match (expr into string)

• If true, return Result Ok(a_program + a_args ⇒ command ⇒ stderr ⇒ string).

• Otherwise, return Result Err(message).

This macro is useful for runtime checks, such as checking parameters, or sanitizing inputs, or handling different results in different ways.
