 * Returns false if the argument expression is a lambda and the expected type

 * Returns true in all other cases.
 * 
 * This serves as a shortcut to rule out decision path's where a method is overloaded
 * and one of the overloads accepts a function type but the other doesn't. In those cases
 * it is not necessary to compute the type of the lamdba expression twice.
 * 
 * An example for this pattern is {@link IterableExtensions#filter(Iterable, Class)} vs
 * {@link IterableExtensions#filter(Iterable, org.eclipse.xtext.xbase.lib.Functions.Function1)}.
