+Since Whitespace ignores [VTab] as a comment character, and since the
+Whitespace VM is a superset of the VVhitespace VM, all valid VVhitespace
+programs are also valid Whitespace programs, though the task of locating a
+suitable Whitespace interpreter is left for the reader.
+
+--------------------------------------------------------------------------------
+
+Quoting from the original Whitespace tutorial which I used as language reference:
+
+ The programmer is free to push arbitrary width integers onto the stack.
+
+I have yet to find a Whitespace interpreter which successfully implements that
+statement.
+
+Since I wanted to implement bitwise logic functions, this broad definition
+posed a problem. For example, how many `1`s should be in the output of the
+expression `NOT(0)`? Should the expression `NOT(0) == NOT(0)` always be true?
+
+VVhitespace sidesteps the problem by declaring all integers to be 64-bits wide.
