Well thanks for the tutorial man... but you obviously 
didn't read my previous posts...

Object orientation exists for a purpose, and no, Javascript 
isn't  "true" OOP, but close enough to be able to use the 
most fundamental principles of OOP, for self explanatory 
reasons.
I guess it comes down to a matter of taste and preference.
I thought creating a constructor method was a clean and 
easy way of doing "extended" functions initialization.
But sure, assigning DynLayer as a method and then calling 
it works too... :)
