You can do # because # is an issue, and do # simply returns #: Here's from the console:
>> trace on
Result: (unset)
>> do #
Trace: do (word)
Trace: # (issue)
Result: # (issue)
== #
So # print "hi" prints hi because # doesn't print anything. You could equally do "Here's
a string" print "hi", which also simply prints "hi":
>> "Here's a string" print "hi"
Trace: "Here's a string" (string)
Trace: print (word)
Trace: "hi" (string)
hi
Result: (unset)
