[C2hs] can't access struct field with name 'type'

19 Apr 2004

      A bit of an irritation I've run into is that one cannot say:

valueType <- {# get GConfValue.type #} value

You see, GConfValue is a C struct like so:

struct GConfValue {

  GConfValueType type;
  ...
};

where GConfValueType is a C enum.

The c2hs tutorial seemed to indicate that you could do this
http://www.cse.unsw.edu.au/~chak/haskell/c2hs/docu/c2hs.html#toc3.8
(see the example)

however c2hs (version 0.10.17 & 0.12.0) complains:
GConfValue.chs:156: (column 36) [ERROR]
...
...
...
Syntax error!
  The phrase `type' is not allowed here.
Presumably 'type' is a reserved token because 'type' is one of the c2hs
directives. Would it be terribly difficult to make the directive names
not special in cid contexts?
