A new feature for RegexSnippets
I noticed that several people on the regex lists post working snippets with their regex's to demonstrate how the pattern is used in code - and to prove that it works ;-), so, I decided to add another form to RegexSnippets that will allow you to enter code and compile+execute it on the fly. By using this feature a user can test the pattern in the tool, then bring up the new form, write a harness module and compile it in the tool before adding it to their post. Here's a picture of my progress to date:

As you can see, I'm certainly no UI guru! ;-) The form will come with 5 or 6 standard templates for common things such as enumerating a Matches collection, Replacing etc.
