As it is, this is completely unreadable and unhelpful to someone who's trying to learn (which seems to be the goal of this wiki). [[User:Nihil|Nihil]] ([[User talk:Nihil|talk]]) 01:59, 8 September 2014 (UTC)
:I wrote it and I'll remove it. At the time either python did not allow for the passing of a function as an argument to an other function, or I did not know about it. Anyway back then using a lambda seemed like the only way and the nesting was necessary as one can not assign variables in a lambda.[[User:Grondilu|Grondilu]] ([[User talk:Grondilu|talk]]) 17:33, 1 September 2021 (UTC)
==All formulae rendered invisible to many browsers by white-space tidying on April 29 2016==
White space edits on the task page, including the injection of spaces around expressions in <math> tags, have rendered all formulae in the task description completely invisible to all browsers which display the graphic file version of formulae rather than processing the MathML (this is, in fact, the majority of browsers). The MediaWiki processor does not currently expect such spaces, and generates syntactically ill-formed HTML if they are introduced.

:I have the same problem: works with Firefox, does not work with IE. A quick look at the contribs of this user shows it's not the first time. I reverted his edit on the RK task, we'll have to check the other ones. [[User:Arbautjc|Arbautjc]] ([[User talk:Arbautjc|talk]]) 06:17, 22 September 2016 (UTC)
:: Sometimes there are useful textual edits mixed in with the under-tested cosmetic tweaks, so repair will, unfortunately, often need to be more partial and time-consuming than a full undo.
:: (Another hope is that a later version of the MediaWiki processor might acquire an expanded range of accepted input patterns, and stop choking on things like the redundant spaces around expressions in <math> tags).
:: In the meanwhile, there is a list of the tasks that were still affected by this kind of issue as of Sep 21 2016, at: http://rosettacode.org/wiki/User_talk:Rdm#Names_of_tasks_still_affected.
:: One or two of those listed have since been manually edited to restore lost visibility of formulae. [[User:Hout|Hout]] ([[User talk:Hout|talk]]) 08:06, 22 September 2016 (UTC)
