Re: [perl #131877] better error message for exit("hello")
Would it be possible to special case when someone passes a string to
exit and give a better error message telling how to write that?
Maybe the error message should indicate what types are allowed.
Better yet, could exit accept a string?
That would be equivalent to `print("hello");exit(0)`.
Very little added value IMHO, but source of potential confusion: How
will `exit($x)` use the content of `$x`, as a return code or as
something to print? You have to check whether `$x` is an integer or not
- and what about floating-point numbers? It could be converted to string
or to int, and at least some programmers will expect the opposite of
what Perl6 is doing.
TL;DR it shouldn't accept a string, that would be worse than throwing an
error.
(IMHO etc.)

In Python one can pass a string to the exit() function that will be
displayed and the program exited.
In Perl 6 I get:
$ perl6
To exit type 'exit' or '^D'
> exit("hello")
Cannot convert string to number: base-10 number must begin with valid
digits or '.' in '⏏hello' (indicated by ⏏)
in block at line 1
