As I understand you offer to make separate syntax representations for
at least four binary operators: + - * / . And possibly for ^ % | ~ &
<< >> < > == <= >= .

But the final result is the same: operands converted to one type and
then operation is performed. By Michael Nelson's proposal you should
covert type explicitly: "print(math.pi * d^2 / to_float(1 << 2))".
By your proposal, conversion is implicit, determined by operator:
"mid = (left [+] right) [/] 2".

I'd prefer avoid adding new operators. Indeed, no operators may
be used at all: "div(mul(math.pi, sqr(d)), to_number(4))"
