Sigils. Once you know them, you'll love them in the Raku Programming Language
summary
Shows concrete Raku syntax: $ @ % & map to scalar, positional, associative, and callable variables with real examples (my $foo = 42, @scores[0], %scores{'ue'}, &cb.roll). Demonstrates twiddles ( . !) for dynamic env vars, method calls and private attrs, and the backslash for sigilless constants. Highlights surprising details: negative index uses $ -1 via -1 star not -1, interpolation rules requiring parentheses for method/sub calls, and that compile-time type checks catch wrong argument kinds before running.
