Sorry, i did misread what actual function you were trying to
access, the problem is that {} isn't really the thing that expands
the variable its the special cases:
->{}
${}
{} by itself simply defines a code block.

One way to solve this without adding a feature like that would be:
${$this->fname} = $this->fname;
${$this->fname}();
or for the oneline purists :)
${ ${$this->fname} = $this->fname }();
wow.. ${} is more powerful than i had originally though.
