Perl has no fixed distinction between "string" and "number". This is a bit problematic for modules like JSON that try to guess such concepts from circumstantial evidence.

My approach is to try to explicitly state whether I want a value to be treated as string or number by performing either string concatenation on it or an addition:

my $string = 3;
my $number = "42";
my $data = {
    string => "".$string,
    number =>  0+$number,
};
