/prog/ - overloading operators

Name: Anonymous 2011-01-31 15:59

why would you overload already existing operators in Sepples instead of inventing your own symbol or keyword to avoid confusion with non-overloaded standard operators?

To make your own classes that represent mathematical entities such as vectors, matrices, quaternions, arbitrary precision data types etc, etc, etc.

Write this in one heavily used library and have fun!



sub infix:<==> ($n is rw, $m is rw) { my $returnValue = ($n != $m); $n = $m = Mu; return $returnValue };

Because C++ doesn't support user-defined operators or keywords, duh.

inventing your own symbol or keyword
The smiley face symbol does this with that, the telephone symbol does that with this.

actually it does

#define (ENTERPRISE X) (const static volatile __cdecl(noreturn) X)

U mena
#define ENTERPRISE(X) (const static volatile __cdecl(noreturn) (X))

U mena
#define ENTERPRISE(X) const static volatile _Noreturn X
_Noreturn is C1x

How about defining a keyword my that would make hax my anus equivalent to anus.hax?

hax my $anus;
VALID PERL CODE

Generic code, bitches.



template<typename MyAnus>

void hax(Anus& anus)

{

  anus ^= 2;

  anus ^= anus;

  anus ^= 21;

}

works for everything that defines ^= operator ([spoiler]NO EXCEPTIONS). I can use it like



  MyAnus myAnus;

  OpAnus opAnus;

  hax(myAnus);

  hax(opAnus);

If i decided to implement custom operators like ^^= and =^_^= then the code above wouldn't compile.

Some typos there(MyAnus = Anus in 1st code section, I left /spoiler tag), but you got the point.

Doing it wrong. You need at least five policy classes, 2 non-class template specializations and the function should be marked:



virtual void hax(Anus***& anus) const __attribute_((deprecated))
