Hi, and welcome to RC :-)
(It's nice to get language authors contributions).
Hi, your permutations example seems to be written to answer more than one task but in doing so becomes a not very good RC code example for those tasks as it shows extraneous answers and code not needed in the task. Far better if you used a library or module import system and tailored each example to the task at hand. I have flagged these examples for attention as I don't think it would be good for RC tasks if this unrelated output from examples was to spread.
The Executable library task specifically asks for the use of a library. --Paddy3118 (talk) 06:12, 8 August 2015 (UTC)
Thanks, I assume you meant the deranged anagrams task, which I have fixed. --Pete Lomax (talk)
