[Haskell-beginners] Unmaybe

[Adrian May]

I seem to have come up with something:

main = putStrLn $ show $
  "Foo".:.100 |:|
  "Bar".:.10 >:> (
                 "Ket".:.20 >^> "Pod".:.1 |^|
                 "Zig".:.30
                 ) >:> "Erm".:.15
                                          >@> "Nuk".:.50
                            >@> "Din".:.30

says:

1:Foo=0.0->100.0
2:Bar=0.0->10.0
3:Ket=10.0->30.0
4:Pod=30.0->31.0
5:Zig=10.0->40.0
6:Erm=40.0->55.0
7:Nuk=31.0->81.0
8:Din=30.0->60.0

I'd best give names to those forks though otherwise the whole project plan
will break whenever I insert a new one. Can I give a parameter to an
operator? Like:

task1 `fork "name"` taskb

or:

task1 ( >^> "name" ) taskb

Adrian.
