/**
 *  for infix expressions, we ignore implicit coercions for now. For arithmetic
 *  operators, we assume the type of the entire expression to be the same as that
 *  of either operand. For comparison operators, we require operands to have
 *  the same type, and assume that the result is a boolean. Note that Assignments
 *  are also InfixExpressions and that some property-get operations show up as
 *  InfixExpressions for which the operator is GETPROP.
