Here's a puzzle. Write a short phrase to generate the character list '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
Some proposed solutions are:
a.#~2|i.&0"1 a./:@,"0 _'09AZaz'
a.#~~:/"1(i.256)</a.i.'0:A[a{'
a.{~I.2|I.48 10 7 26 6 26
But I can't believe there isn't something shorter than that.
