[iset] new instruction

[alex]

A new instruction:
  Thought: Think of the first thought in your head, and transcribe it as
source code.
  http://instructionset.org/instruction/16/

I hope no-one is thinking anything rude when they read the instruction.
If so, please close your mail client, take a sip of water, clear your
head, and try again.  Or bury your shame and implement it anyway...

As ever, please contribute your own instructions:
  http://instructionset.org/instruction/suggest/

If anyone is interested in helping out with the instructionset,
developing it a bit, helping run it/promote it or whatever then please
get in touch.  It's not a commercial endeavour but it would be nice to
find ways of opening it up and getting more people involved with
contributing code.

cheers,

alex
