Indeed, you can. The first thing to learn here is that the hash (#) signifies a literal symbol. So, #a is a symbol, whereas 'a' is a string (of length 1 and containing the character $a).
The second thing to learn is that the dollar sign ($) signifies a character value, so $b is the value of the character "b" and $c is the value of the character "c".
#() signifies a literal array created at compile time.
Thus, #($a #a 'a' 1 1.0) is an array that contains the character $a, the symbol #a, the string 'a', the integer 1, and the floating value 1.0). Easy peasy.
