The docs give some good examples of one use of Directive: to avoid
nested graphics directives. Thus the example
Plot[{Sin[x],Cos[x]},{x,0,10},
PlotStyle->{Directive[Red,Dashed],Directive[Blue,Thick]}]
from the "home page" of Directive, although wordier, is to my eye
easier to read than the equivalent:
Plot[{Sin[x],Cos[x]},{x,0,10},
PlotStyle->{{Red,Dashed},{Blue,Thick}}]
The longer and more numerous the directives are for the various elements
of a plot or graphic, the more useful Directive becomes in untangling
the syntax for the eye.
