Re: [WebMacro-user] A WM brain bender

Continuing the conversation with myself ...

Another interesting option would be to change the #eval directive to 
work with Strings as well as Macros.  (I would automatically convert the 
String to a StringMacro).  This would be a simple change.  The only 
downside is that it might make it a bit harder to catch some errors.

Then you could simply say:

#eval $content.Data using { "contextData": $someData }

This is kind of cool.  You could even do stuff like:

#eval "Hello, $userName" using { "userName": $User.Name }
