(ii) If "[pads|" is a lexeme, then some list comprehensions become
illegal,
I am not myself a TH or QQ user, but it has always bothered me
slightly that the syntax for them steals some valid list comprehensions.
Of the alternative syntaxes you suggest...
My gut feel is to go with [|pads| ... |].
... this one feels the nicest, because [| |] is an ascii
approximation of the common syntactic brackets used in semantic
specifications. In some ways, to make the correspondence even closer,
pads [| ... |]
might be even better, although I realise that this might present new
problems.

Malcolm
