You could on page 38 mention, that the qualified name of a static method can be used as a function to be used later.
Example:
user=> Math/sin
#object[user$invoke__Math_sin__202 0x7573e12f “user$invoke__Math_sin__202@7573e12f”]
user=> (*1 1)
0.8414709848078965
comparable to the access of static fields.
