Portability of VeLa code with localised numbers

[dbenn]

The same code will work in one locale but fail in another, e.g.

x is -4,2

vs

x is -4.2

The idea originally was to allow flexibility via localised numbers.

While continuing to allow this, should we also always translate localised decimal point characters such as , to . internally and apply numeric parsing via the same locale?

This would be very helpful.

I'm a little surprised I didn't see this clearly before.

One approach is to do what we do now with an additional attempt to use the non-localised parsing in the exception catch block.
