How can I dump an expression into log and execute it

[Delorien via Digitalmars-d]

Hi,

I have a C macro, which takes an argument, log it and call a 
function.
So, if I had a source code like this:

{
   _logfx(x + 10);
}

the actual code would be

   DebugLog("x + 10");
   fx(x + 10);

Can I make similar tricks in the D language?

Thank you.
