Is there a perl6 counterpart of powershells get-member to "analyze" a variable(-object)?

Question

Question: Is there/What is the Perl6 counterpart of Powershells get-member to "analyse" the attributes of a variable?

Explanation: In Perl 6 you can get properties/attributes of a variable, e.g.:

my $num=16.03;
say $num.numerator;   # output: 1603
say $num.denominator; # output: 100
say $num.nude;        # output: (1603 100)
say $num.WHAT;        # output: (Rat) 

How can I find out, which attributes/properties (numerator etc.) and methods/functions (WHAT) a variable has?
In Powershell I would pipe the variable to get-member, like: $num | get-member and would get all properties and function displayed.

Answer 1

The best way would be to consult the docs for whatever type .WHAT told you, e.g. https://docs.perl6.org/type/Rat for Rat.

If you must have it programmatically, you can ask the object for its methods with .^methods.

> my $num = 16.03
16.03
> $num.^methods
(Rat FatRat Range atanh Bridge sign sqrt asech sin tan atan2 acosech truncate

You can similarly see the attributes ('properties') with .^attributes, but any that you should access will have accessor methods anyway, so you shouldn't really need to do that.
