[plt-scheme] trace forms?

May be the Debug button of Drscheme can be useful for you. It allows stepwise evaluation, breakpoints to be set and cleared and so 
on. This functionality is available without corrupting your source code with tracing command. All functions speek for themselves; 
you dont need a manual to use it. In my opinion it's a fine tool.

  Hi,

  In Chez Scheme, there are trace forms for let and lambda (trace-let,
  for example).

  It is pretty convenient. Is there something like this in MzScheme?

  How difficult is it to implement something like this?
