come on codemirror, highlight this thing.

lol. omg

I've just submitted with Elixir 1.6, please try again

Dare you to solve my kata ? : https://www.codewars.com/kata/advanced-calculator

;-) TDRS

You can block eval by eval = None

>>> eval('1+1')
2
>>> eval = None
>>> eval('1+2')
Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    eval('1+2')
TypeError: 'NoneType' object is not callable

Well it got it's rank due to popular votation, perhaps you can raise an issue to re-rank this kata on the github page of codewars I think that if you got enough backup it can be re-ranked in some weeks. To make it easy try to bullet-proof your code.

Noted, thanks!

Yeah, but then what if they call it "_keys" or "sdkfjhdskf"? There's no real way of making a generalised test for security; you'd need to simulate a real human hacker to be completely sure.
