Not exactly true. In XHTML (i.e. HTML >= 4.0, IIRC), it SHOULD have an end tag

Using a Place or a Place-Channel as a sync event returns the value of a
place-channel-get and not the Place itself.
Most events return the actual `thing' which one sync'd on. This is not
true with places and channels, one gets the message itself.
The conundrum is identification of which Place /

I think you want handle-evt, eg:
(sync (handle-evt p1 (lambda (x) (list p1 x))) )

Can a program running in Racket VM introspect on itself to determine the
names and versions of PLaneT packages that the program uses?
I tried poking around with environment introspection, and trying to
follow module use graph that way, but no luck so far. Maybe this is
something that modules

in the reference, I see the _array function, but I don't understand well, when i try to do, always output errors, can anyone give me an example? here is my test in REPL:racket@> (_array _int 3)#racket@> (array? (_array _int 3)) ; why?#fracket@>

_array produces a ctype, not an actual array itself. To get an array you can
create one with malloc or you can call a C function through the ffi.
If you use malloc then you get back a generic # type which you can
convert to an array using ptr-ref as per the docs:
"Since an array is treated like
