refactor getter method to get property

[mick62]

Hi,

another useful (and needed) refactoring is the change from:

class A {
getProp(): Y
{ return expr }
}
x = myA.getProp()

to

class A {
get prop(): Y
{ return expr }
}
x = myA.prop

Btw. the counterpart 'setProp(val)' to 'set prop(val)'
might also be of interest although we use immutable objects most of the time.

Thank you in advance

I think that's a very good suggestion, thanks @mick62

The tricky bit (especially in JS) will be to find and update all references to the method. Something that may require #275 to be addressed first maybe.

In any case, I'm turning this into an issue to track the interest 👍
