This is quite possible. The language I'm parsing is very whitespace
happy (sometimes!). No this was not fun to parse. So it could be that
the lexer passes:

COMMENT EOL SOME_THING

And of course when I try to print the text of SOME_THING, there is no
hidden before.

Any suggestions?

Perhaps using tokenrewriteengine would work because that would mean I
could keep track of the index of the last token printed and then print
all hidden things from there till now. But this doesn't sound too fun.
