but the current CVS versions of hat-detect and hat-check are slightly
broken (they don't deal correctly with DoLambda 0x5).
Can you tell me what the structure of DoLambda is so that I can  
update NodeExp.hs to deal with it... hat-check says it has no  
pointers except for source position, and parent...
'DoLambda' is not an expression.  It is a specially distinguished kind
of FileNode like so:

    Root            0x0
    Unevaluated     0x1
    Entered         0x2
    Interrupted     0x3
    Lambda          0x4
    DoLambda        0x5

See include/art.h and src/hattools/LowLevel.hs.

I think it can appear anywhere a "Ref Atom" would be valid, e.g. as
the 'value' field of an ExpValueUse.
