This is a very big change. If FunC has `.methods()` and `~methods()`, Tolk has only dot, one and only way to call a `.method()`. A method may mutate an object, or may not. It's a behavioral and semantic difference from FunC. - `cs.loadInt(32)` modifies a slice and returns an integer - `b.storeInt(x, 32)` modifies a builder - `b = b.storeInt()` also works, since it not only modifies, but returns - chained methods also work, they return `self` - everything works exactly as expected, similar to JS - no runtime overhead, exactly same Fift instructions - custom methods are created with ease - tilda `~` does not exist in Tolk at all
