If you take a look at this page's source #[a(target="_blank", href="
https://github.com/jadejs/jade/blob/master/docs/views/reference/interpolation.jade";)
on GitHub],
you'll see several places where the tag interpolation operator is
used like so.
.quote // this is raw text so the .quote means nothing to jade, only string
and tag interpolation works here
p Joel: !{riskyBusiness}
p.
This is supposed to just be text inside a p tag.
- import std.uni : toUpper;
- string msg = "not my inside voice";
p This is #{msg.toUpper()} &lt;- #[a(href="#") upper case] characters

// Following is as4df, its the last tag
as4df
