I like the later for the reasons you mentioned.
I also use a couple of other conventions to solve some name conflict
problems
I've run across:
- instance variable names begin with an underscore and a lower case
character.
Example:
Point =
{
_x = 0,
_y = 0,
_z = 0,
}
- method names begin with a lower case character and contain an underscore
for
every argument the method accepts.
Examples:
function Point:x()
return self._x
end
function Point:x_(x)
self._x = x
return self
end
function Point:x_y_z_(x, y, z)
self._x = x
self._y = y
self._z = z
return self
end
This is to avoid name collisions between instance variables and methods of
different types. In the example above there's an instance variable "_x", a
getter method "x" and a setter method "x_" with no name collisions.
