I wonder if hamlet could leverage haskell-src-exts-qq, which defines quasiquoters for haskell code.  I've used it myself, and although it's been a while and I'm a bit hazy on the details, I remember that it worked rather well.  One gotcha I remember is that it didn't usually know correct fixities for operators etc, which could lead to quite confusing errors.  This may have improved since I last looked at it, though.

Of course he was aware, someone wrote a message six hours ago =).  I think it's doable, Matt.

Cheers,

Contrary to popular belief, I don't read my email at every hour of the day ;). In fact, I can guarantee you that I won't see any email from sundown on Friday till sundown on Saturday[1]. Anyway, I have a few concerns regarding haskell-src-exts-qq: 1) It's a heavyweight dependency. 2) I assume the parsing time of this will be significantly larger than the current parse code. (This is the most minor of my issues.) 3) I don't know how well it will interact with the debug version of the templates. 4) It's not necessarily desirable to make the interpolation so complex. Compare for instance Haml versus Django templates: the latter purposely allows only a limited form of interpolation to keep templates simple. I'm not vetoing this, not by a long shot. I'm merely bringing up the issues I've been thinking about for the past 30 hours ;).
