Re: A WM brain bender

Looking back at the old TemplateTool code, it does what you want, but 
not in a particularly elegant way:

#set $m = $Template.fromString($content.Data)
$m.eval({ "contextData": $someData })

For some reason the MacroTemplate class doesn't implement the Macro 
interface.  This would be a simple change that would allow you to say:

#set $m = $Template.fromString($content.Data)
#eval $m using { "contextData": $someData }

I could make this change if anyone is interested.
