+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

+  local _fn_0 = _base_0.world
+  x = function(...)
+    return _fn_0(_base_0, ...)
+  end

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