Unfortunately that usually means that you need to let the IO type
filter down from the top level to all fns which need to print something.
Then you can emit a message perhaps in the same function which
reads the files.

Or is it perhaps a buffering problem? =20

Hello All,
=20
I wrote a small haskell program that amongst other things parses
some files to manipulate them. During runtime I want the program to
output information about the status every time another file is parsed.
That doesn't work, the output appears much later, mostly not until end
of program. But I need these outputs at that specific time, so what can
I do to manage it?
=20
Thanks
