How do you then pass the primitive as one? Like passing EQ/EQUAL/EQUALP to FIND/POSITION family of functions?
Oh right, I understand the question a little better Here is that impl: http://larkc.svn.sourceforge.net/viewvc/larkc/trunk/platform/src/com/cyc/tool/subl/jrtl/nativeCode/subLisp/Sequences.java?revision=254&view=markup public static final SubLObject find(SubLObject item, SubLObject sequence, SubLObject test, SubLObject key, SubLObject start, SubLObject end) { // throw type error or allow user to supply a sequence type SubLSequence sequenceTyped = sequence.toSeq(); // find or compile 2 arg signture version of the Test function // if UNPROVIDED use EQ BinaryFunction testFunction = extractBinaryFunc(test); // find or compile 1 arg signture version of the key function UnaryFunction keyFunction = extractUnaryFunc(key); //unboxers (or force user to supply an int if not coercable) int startTyped = extractStart(start); int endTyped = extractEnd(end); // use the specific Seq find/5 impl SubLObject result = sequenceTyped.find(item, testFunction, keyFunction, startTyped, endTyped); return result; }
