Allow user-defined variable markers?

Today, the plugin looks for double curly brackets ({{ and }}) around variables. Without these, it doesn't recognize a string as a variable.

Do people already use double curly brackets in their designs, and would have to change them for the plugin? If they do, maybe it would help to let users define the surrounding symbols.

most templating engines these days I've come across use the double curly braces.
