class Compiler does Systemic {}

Built-in class for providing compiler related information. Usually accessed through the compiler attribute of the $*RAKU dynamic variable.

say $*RAKU.compiler; # OUTPUT: «rakudo (2020.02.16.g.28.bd.4247.a)␤»

Note: Before Rakudo version 2020.1 this was only available through the compiler attribute of the $*PERL dynamic variable. Since Rakudo version 2020.1 this is available through both the $*RAKU and the $*PERL variables.
