[Hat] Fw: another wish for Hat

[Malcolm Wallace]

Anthony's original message, containing his wish list for Hat:

	"A technical document defining the format of Hat traces, so
	 that implementors of Haskell can add native support for Hat
	 to their respective systems."

	It also solves the problems of:

		* maintaining and distributing a separate
		  tracing version of the Haskell codebase;

		* maintaining a separate Haskell source-source
		  transformer and front-end.

	Some extra benefits:

		* Traces coming from Haskell implementations
		  would be from well-typed programs;

		* The somewhat-invasive nature of Hat on a Haskell
		  codebase could be considered a deterrent to its
		  widespread use; this would no longer be the case.


	I understand that native support for Hat will be part of yhc;
	this would be a good opportunity for "Hat insiders" to put
	together such a document - the implemetation in yhc could
	then be used to vaildate it.


	Regards,

	Anthony
