Lua OOP classes usually end being:
|
||
|
|
a) multi-file libraries, too difficult to understand
|
||
|
|
b) very small libraries, not very powerful
|
||
|
|
|
||
|
|
Middleclass attemps to be a mid-sized library (100 lines of code, on a single file), with clean, easy to understand code, and yet powerful enough to be used in most cases.
