Coding conventions for writting cfc's in CF9?

Question

With the new ways of writing CFC in CF9, what are some of the coding convention new to CF9?

Here are some I can think of...

• always use LOCAL scope
• always include init() method that returns itself, since New will call init() if found.
• do not put required arguments in init() if it is an ORM entity, otherwise expect Exceptions...
• always use THIS.setXXX in where XXX is property name inside init(), so that it will call the implicit setters or custom setter if available.
• abandon the pre-CF8 INSTANCE scope convention, see: http://henrylearnstorock.blogspot.com/2009/08/should-we-abandon-instance-scope-in-cf9.html
• no output=false for component and functions in script style CFC, see: http://www.coldfusionjedi.com/index.cfm/2009/8/26/Ask-a-Jedi-Impact-of-whitespace-and-script-based-CFCs
• use the cleaner and more efficient isNull(arguments.optionalArg) instead of isDefined()

Answer 1

do we still need to set attribute output=false for component and functions in script style CFC?

I wouldn't think so. <cfscript> by its nature suppresses any whitespace and needs writeOutput() in order to have any output at all.

Answer 2

I agree with your recommendations.
