NAME

String::Numeric::Whatever - It's a test implement to ignore the difference between <=> and cmp

SYNOPSIS

 use String::Numeric::Whatever;
 my $str = String::Numeric::Whatever->new('strings');

 say q|Succeeded in comparing with strings by 'eq'| if $str eq 'strings';            
 say q|Succeeded in comparing with Int by 'ne'|     if $str ne 100;            
 say q|Succeeded in comparing with Int by '!='|     if $str != 100;
 say q|Succeeded in comparing with strings by '=='| if $str == 'strings';
           

DESCRIPTION

INTRODUCE

If you have knowledge of other language, You may think like that.

Why strings can't be compared with using ==?

I can't answer the reason why, but can give you this module.

It provides us comparable object with using ==, eq or whatever!

CONSTRUCTORS

I'm sorry that you have to call constructors before getting the benefits of this module.

new()

There is no validation. accepts all types of SCALAR

 my $str = String::Numeric::Whatever->new('strings');
 my $num = String::Numeric::Whatever->new(1234);

tie()

or you can set like this:

 tie my $str => 'String::Numeric::Whatever', 'strings';
 tie my $num => 'String::Numeric::Whatever', 1234;

THEN

Now you can compare the values with using any operators in below:

 < <= > >= == != <=>
 lt le gt ge eq ne cmp

After you assigned the constructors, you don't have to care about whatever this is a string or number.

So you can write like below without warnings:

 say $str if $str == 'string';   # strings 
 say $num if $num ne 0;          # 1234
