static this() blocks: executed when a thread a starts (the program has
at least one thread: the main thread); so you can put initializations here
~static this() blocks: counterparts of 'static this', executed once for
each thread that is terminating
shared static this() blocks: executed once per program (executed by the
main thread)
~shared static this() blocks executed once per program when the program
is terminating

That's the lambda (ananymous function) syntax.
The "rand" key of an associative array is being associated with the
function after the ':' character. In the code above, the function
creates a new Atom object. So, when the following code is executed:
primitiveSymbols["rand"]
the same lambda would be returned but the execution of that lambda as
the following
primitiveSymbols["rand"]()
would return a new Atom which would make a call to the rand01() function
and get a new random number from the same 'rnd' object.
