I would like to see closures implemented in CFML. Closures are a great fit for a dynamic language like ColdFusion. They are becoming a fundamental programming technique, and their heavy usage in languages such as Javascript, Scala, Ruby, and Groovy indicate that they are, indeed, mainstream. Let's not let CFML fall even further behind.

I'm no language designer, so I don't know what a closure implementation *should* look like in CFML. I have, however, discussed the subject of ColdFusion and closures here:

Closures in CFML is a feature that's long overdue. For my detailed commentary, check my response to the MXUnit blog post

Left a longer comment, but I want closures that are really just object/function pointers. So that the passed function reference maintains its link to it's CFC/object. Also in the comment I talked about passing arguments to pass to the callback to create generic callbacks. Thanks

Yeah, I plan to propose a closure syntax to the CFML Advisory Committee and I expect Railo will implement a version to get feedback from CF devs.

I love the thought here. Consider anonymous functions & closures please :)
