Question about hugs´s DEBUG_SHOWSC
Fri, 13 Apr 2001 00:48:04 -0500
hi haskellers ...
I´m trying to use the hugs´s flag DEBUG_SHOWSC. Everything seems to work
fine, except for one(simple?) detail:
When you use Int or Double literals, hugs always add extra variables,
related to the fromInt/fromDouble aplication.
f = 666
should be translated to:
f = fromInt 666
but hugs returns :
f = fromInt v35 666
What is the var. v35 for???, the function fromInt receives just one argument.
If the function has parameters, the resulting function has extra-parameters,
which seems to be out-of-place in both sides of the binding ...
here you are a couple of examples:
f x = 666
generates the output:
f o2 o1 = fromInt o2 666
And the reported type for f is: Num a => b -> a , which is inconsistent with
the previous result.
f x = 666 + x
f o2 o1 = (+) o2 (fromInt o2 666) o1
which has similar troubles to the previous example.
What are these extra-variables for? Are they a debug-feature? what´s the
And finally, the obligated question: how can I avoid them? I suppose that
I have to take a look at the source code, but: what´d be the part which
is responsible for this(parser,static,type... no please,compiler)?
Thanks in advance.
