[plt-scheme] [scribble] syntax quasi/unquote

Hi,

I know that I can use @SCHEMEBLOCK to render scheme code that uses #` and #, (in macros).

However, I'm not able to render text @SCHEME[`#] or @SCHEME[#,]. Why is that?

Also, there doesn't seem to be a @SCHEMEBLOCK+eval or @DEF+int, so I don't know how to have that code evaluated (and typeset as @SCHEMEBLOCK does)

Thanks,
