Syntax for assignment

[BraedonWooding]

Related to #8, #11

Current assignment rules dictate;

X.a = 5
// You can specify type
X.a : int = 5

However the syntax for defining a literal or a 'definition' is x : T = a which can be shortened to x := a, should we also follow suit and make assignments X.a := 5?? Or should we just automatically infer and make it just ? = ?? everywhere i.e. x = a or X.a = 5 or X = B::().

If so then what do we mean for X = B::() if X is defined vs not defined, are we assigning the label 'X' or are we assigning what X points to i.e. something more like *X = B::()?

Could we also allow X : B { ... } rather than requiring X = B::() { ... } since I don't like X = B { ... }, this would also basically help with backwards compatibility of v0.3 however we aren't ensuring that we have to be compatible just yet.

Very interesting, and I'm not settled on an answer yet.
