This above bit of code is trying to delete all elements at once 
by assigning a null to colors associative array. Interesting 
thing is the write output after assigning null to colors variable 
shows "[]".


Here is the output.

Before:
["blue":"నీలం", "red":"యెరుపు",
"white":"తెలుపు", "green":"పచ్చ", 
"black":"నలుపు"]
after:
[]


So primitive types can never be null ? An null assignment would 
set the primitive type variable to a default value ?

Check for null with (x is null) not via printing to stdout.

In most cases instead of checking dynamic arrays for null, it's 
better to use std.array.empty.
