+	This procedure reads the code from stdin, strips all unrelated
+	characters and returns an array of tokens on the stack, so the toppest
+	element is the firstest
+
+	Note that since its algorithm this function should be called with empty
+	stack
+
+	TODO: rewrite this function so it won't depend on empty stack
