[erlang-questions] io_lib printable list

[Yuri Shefer]

Hi all,

I have a silly question.

Why io_lib:printable_list() accept characters only in the quotes? Is it
needed even for the numbers?

8> io:getopts().
[{expand_fun,#Fun<group.0.56199974>},
 {echo,true},
 {binary,false},
 {encoding,latin1}]
9> io_lib:printable_list(1).
false
10> io_lib:printable_list("1").
true

Best regards,
Yuri
