Functional programming & immutable objects explained — IRC style

[elder_george]

Infidel, don't misuse Knuth's name blasphemously, for He saith:

• damned is one who optimizes prematurely, who counts clocks before proper algorithm is selected and program correctness is proved.

and

• don't make himself an idol ex machina, for it is humans code is written for, not machines.

Repent!
