Proposal: Support for Proper Modular Arithmetic

   I have researched and drafted a proposal to address the deficiencies 
with the remainder operator (%) and introduce support for the proper 
mathematical modulo operation.

In summary, the % operator is commonly used and referred to as a mod by 
developers, but is fundamentally broken because it takes the sign of the 
dividend.  The proposal outlines two alternative algorithms (Euclidian 
and floored division) that are commonly used within other languages and 
suggests either new Math.mod or .floorMod methods, or new infix operator 
such as %% or mod to address the situation.
