Thanks!

This means that your code is too long. Note that this kata is a code golf kata, which means that it has a limit of code length:

Lastly, this is code golf, so your solution has to be less than 71 characters.

What's the meaning of this - 'Code should have less than 71 characters, but has 608 characters instead.'?

"Expected actual value true to approximately equal expected value false (accepted relative error: 1e-9)" as if booleans can not quite be the same as another boolean but still be close enough

Probably not an issue but it's definitely worth mentioning :)

Added very simple generator to prevent hard coding.

.

There are still at least 2 cheese in the solutions ;-)

Just randomizing the input is not enough, you need to test more functions and randomize the functions themselves too.

Needs random test with deeper nesting and cases mentioned below in the issue.

My solutions probably shouldn't have passed

Needs Random Tests.
Needs cases like }{

click	The first part of the combination is correct
click-click	The first two parts of the combination are correct
click-click-click

in the table... ;p

The description says this already.

It actually just says "sounds you can hear", but I guess that doesn't matter anymore since the safe properties are now hidden so there's no real ambiguity.

Approved :)

Good idea. Done. Thanks.

Your solution is now invalid ;-)
