[wxhaskell-users] strictness annotations on wxhaskell

[<72...@in...>]

Hi Daan, I hope you remember me, Jose David. I was developing my own yahu-like 
library. I have realized you use strictness annotations ('!' symbol) in the 
event and font algebraic data of WXCore, but no in more complex data, like 
Layout. Have you special reasons for this, or perhaps is performance-irrelevant 
to make strictness annotations in higher level data? I suposse it's because the 
way you modify the layout - maybe it is worth to no evaluate combinator-
replaced layout options. I ask you this stuff because I found almost no 
references about in the haskell report, the mailing list nor the hawiki.

By the way, do you know it is worth to make strictness annotations on multi-
argument data constructors? All I have found about this is that GHC unboxes 
single argument, strict annotated data constructors.

Thanks in advance.

Jose David.
