Apparently using warnings and strict is important.

What's wrong with C< print "got here" if ($debug);>
	rjbs: well, the extra parens?
	nothing
	but you have more power in the debugger

useful to have Term::Readline, of course
or there are lots of IDEs

FIRST SEVEN ESSENTIAL COMMANDS
	rjbs: too many commands for one slide!

	s - single step, next line, step into subs
	n - same, step OVER subs
	r - non-stop until current sub's return
	... changed slide before I could finish

font hell: term was too small-fonted, too long time to change.
note to self: always check font sizes on terms if they will be used

	x - display var value

	apparently lexicality matters? unclear, but he had to correct a
	lexicality-related error

	c - continue (possibly until given line# or sub)
	a - set an action -- perform given code at given line number
		a linenumber code

talk didn't get much further. basically ran out of steam, ended.
