in reply to Array interpolation in Rakudo

The language has changed in that respect - arrays and hashes only interpolate into double-quoted strings if they end in a postcircumfix, that is any bracketing characters coming after an expression.
say "array: @array"; # interpolates nothing say "array: @array[]"; # interpolate all elements say "array: @array[1]"; # interpolate one element say "array: @array.sort"; # no interpolation, does not # end with something brackety say "array: @array.sort()"; # interpolates sorted array

Rakudo implements those cases according to the specification.
