[Haskell-cafe] Haskell type declaration summary

[Andrew Butterfield]

Dear Brandon,
 thanks for that - the echo :browse solution is ideal because I can easily write a short Haskell program
to filter out the type declarations from the output.
In fact it becomes easy to extract other kinds of declarations as well.

Here the offside rule really is my friend.

I'll post a fully worked solution once I build it.

Thanks, Andrew
