Implement Strict Numbers

Change By:	Henrik Lindberg

Background
---
* < 3.x && 3.x without future parser - all values are strings, and numeric operations has a variety of problems
* 3x future parser has a hybrid string / number auto type conversion. Early versions of the future parser had paradoxes in handing numeric values that were fixed late in the 3.x series (use 3.8.x with future parser).
* 4.x is the same as 3.x future parser

The experimental current 4x evaluator also has this, but with currently fixed paradoxes in this handling automatic conversion between string and number . It continues to be a problem balancing between "being helpful" and "being correct and free of paradox".

It would be much cleaner to never automatically convert between numbers and strings (except possibly at boundaries; converting numerical facts in string form .

This Feature
---
When {{\--strict}} mode is on, arithmetic on a {{String}} leads to real numbers) a warning or error as dictated by the mode . When strict is 'ignored' auto conversion still takes place.

Depends on
---
This feature depends on PUP-5889, that there is a strict flag, and PUP-484 since it is currently not possible to convert values.
