Bound functions will avoid creating an anonymous function unless necessary.

```moonscript
|
||||||
|
x = hello\world
|
||||||
|
```
|
||||||
|
|
||||||
|
**Before:**
|
||||||
|
|
||||||
|
```lua
|
||||||
|
local x = (function()
|
||||||
|
local _base_0 = hello
|
||||||
|
local _fn_0 = _base_0.world
|
||||||
|
return function(...)
|
||||||
|
return _fn_0(_base_0, ...)
|
||||||
|
end
|
||||||
|
end)()
|
||||||
|
```
|
||||||
|
|
||||||
|
**After:**
|
||||||
|
|
||||||
|
```lua
|
||||||
|
local x
|
||||||
|
do
|
||||||
|
local _base_0 = hello
|
||||||
|
local _fn_0 = _base_0.world
|
||||||
|
x = function(...)
|
||||||
|
return _fn_0(_base_0, ...)
|
||||||
|
end

end

Explicit return statement now avoids creating anonymous function for statements
|
||||||
|
where return can be cascaded into the body.

There was always a little confusion as to the rules regarding whitespace around it and it was recommended to always add whitespace around the operator when doing subtraction. Not anymore. Hopefully it now [works how you would expect](http://moonscript.org/reference/#considerations). (`a-b` compiles to `a - b` and not `a(-b)` anymore).
