Re: Metamethods: WHERE

If you want to find out if two variables are bound to the same data, there is an operator for that my $a = 3; my $b = 3; say $a =:= $b; # False my $c := $b; say $b =:= $c; # True On Wed, Feb 12, 2020 at 7:27 AM Aureliano Guedes wrote: > Thank you. > > So, I'd like to find

Thanks for the tip! This might be useful to data analysis tools. On Wed, Feb 12, 2020 at 11:01 AM Brad Gilbert wrote: > If you want to find out if two variables are bound to the same data, there > is an operator for that > > my $a = 3; > my $b = 3; > say $a =:= $b; # False > >

Re: Metamethods: WHERE

Thank you. It really helps. Then I go further to understand and I find interesting. The same applies to int 3. > 3.WHERE 94821123453912 As expected, is different from str 3 > "3".WHERE 139904951827592 But the same to $a. > my $a = 3; 3 I suppose that the constant 3 is created only when called.

Metamethods: WHERE

What "WHERE" should return? I was trying to find a method to return the memory address of some data. Then I find the WHERE statement. https://rosettacode.org/wiki/Address_of_a_variable#Perl_6 https://docs.perl6.org/language/mop#WHERE Then I tested it. I created $a, $b and $c, where $c is binded

Re: Metamethods: WHERE

Thank you. So, I'd like to find a way to test if two variables are bound or not, especially concerning their memory address. If the address is not fixed for a lifetime, I must be able to test it in just one cycle. > $a.WHERE == $b.WHERE # I expected FALSE True To a bound variable, I expect
