In the following code I have written in an interpreter of mine is:

  Triple variable assignment operators:

     !!=  assign not value, for example: x!!=10
     &&=  assign and value
     ||=  assign or value
     ++=  assign addition value
     --=  assign negative value
     **=  assign multiple value
     //=  assign division value
     \=  assign integer division value
     ^^=  assign power value
     ^+=  exponentiate value
     ^-=  exponentiate negative value
     <<=  shift left by multiples of 2
     >>=  shift right by multiples of 2

My question is “what other compilers support them”??
