Testing the matrix.org client-server API

Matrix is:

an open standard for decentralised communication, providing simple HTTP APIs and open source reference implementations for securely distributing and persisting JSON over an open federation of servers.

It's pretty fantastic, if you think on the massive problem of fragmentation all across the web. They've created an easy to use API, and you can do a kludgy test using curl from the terminal (*nix, mac, win). See: http://matrix.org/docs/howtos/client-server.html

It's pretty straightforward to do a quick test. I have an account at https://matrix.org / https://vector.im, so I used that to get a token.

	; simple LABELS replacement, expanding to non-recursive code

	; the goal is to provide a simple LABELS like operator
	; which optimizes simple self-tail-recursive code to
	; to a stack-less jump.

	; limitations: does not detect when a call is NOT in tail position,
	; which would require a code walker.
