o ** operator added. It's exponentiation and works with most combination of numerical types (int,float,Gmp.mpq,Gmp.mpf,Gmp.mpz) `** and ``** operator overloading functions added. This introduces one incompatible change: Previously the "pow" function called a "_pow" function in the first argument if it was an object. It has now been changed to also use `** (or, rather, pow() is now implemented using predef::`**()).
* Binary or between a multiset and UNDEFINED is now behaves like
binary or between the multiset and the empty multiset.
o Three pass compiler. An extra pass of the compiler has been added. It is used to properly resolve types in forward referring expressions, and is only run when needed. o #pragma disassemble This directive is now available even in pikes compiled --without-debug.
