在Jade中，如何在不转义返回的字符串的情况下调用函数？

I'm using jade as part of a simple website using golang as the backend.

As part of this I have jade that looks like this:

p#{printf("%s", Body)}

I'm using the package github.com/go-floki/jade to compile this into an executable go template. The function printf is a go builtin that is run once the template is executed.

The problem is that I want unescaped html. The jade doc seems to indicate that this:

p!{printf("%s", Body)}

should work but that just ends up as:

<p>printf("%s", Body)}</p>

Is there a way to escape the function without escaping its argument?

Thanks, Zac
