gollark: Macron 6.τ.283.
gollark: Perl is somewhat more utterly accursuous.
gollark: Macron 6.3.2i will also expand implicit variables to implicit macro invocations. It will pick the best code based on the entropy of its output.
gollark: It will also let you fuzzy match operators.
gollark: Too bad. Macron 6.3 has it now.
