-- Whatever is pasted in the debug console is interpreted as a single command.
-- That means you cannot paste, say, two lines where each is a command.

-- In the debug console, can get the current frame and pass it to main.
-- Setting args has no effect.
f = mw.getCurrentFrame()
f.args[1] = 'Ignored'
f.args[2] = 42
=mw.logObject(f, 'f')
=p.main(f)

-- Can create a child frame with specified args.
f2 = f:newChild({title='MyTitle', args={120,94321,name='hello','{{convert|12|kg}}'}})
f3 = mw.getCurrentFrame():newChild({title='MyTitle', args={120,94321,name='hello','{{convert|12|kg}}'}})
=mw.logObject(f2, 'f2')
=p.main(f2)
=p.main(f3)

-- If main uses Module:Arguments, can pass a table to main.
-- That means argument values may be any data type (normally, arguments are strings).
-- main gets a table, not a frame, so methods like frame:getTitle() cannot be used.
=p.mainargs({11, 22, name='hello', 'more', number=420})

-- See talk for examples of displaying a table.
