Not null check

[Ciumac Sergiu]

How about this piece of code: if (a == null == false) { } Spent some time before figuring out it is a version of if (а != null) {}

[Luc Pattyn]

when in doubt, you can look it up and then clarify by adding parentheses, like so:

if ( ( (a==null) == false ) == true ) {...}

A a clear and sustainable piece of code, this is truly a horror and definitely deserves its place in the Hall of Shame.

can you extend this recursively? only to be very very sure:

if ( ( ( ( ( (a==null) == false) == true) == true) == true) == true)

to shock afterworkers and make compiler happy, one could sometimes say == true and == false :laugh:

Related to the above: flag = bool(int(flag) - 1);

[GibbleCH]

I presume this toggles the flag? And that in this language false is zero and anything else is considered true

Just to make it more subtle add a little "!" at the beginning

if ( !( ( ( (a==null) == false ) == true ) == false)) {...}

:suss:

[Ciumac Sergiu]

This one would be even more subtle :cool:

if ( !( !( !( !(a==null) == true ) == false ) == true)) {...}

[Paladin2000]

How about this one? :-D

if ( true == (!((!(((a ?? true) is bool) ? true : false) == false) == true) == false)) {...}

I used to work at Accenture, they used to make us bracket like that to "Disambiguate" the otherwise very clear logic X|

How about overloading those operators? Also, you might want to use the monad- or the decorator pattern to split that up into multiple lines :)
