Escape '{' and '}' characters in Sail

[c-johnson]

In a sail context, I want to produce the following HTML:

Click!

In sail, curly brackets within strings denote interpolation:

;a(href "javascript:(function(){})()": Click!

Which fails, since the expression is empty

Just looking for a way to escape the curly brackets. Raw tape interpolation in the dojo accepts the \ as a valid escape character, but still includes the \ in the resulting string

"foo {<5>}"
"foo {<5>}"
