 This program takes a single string corresponding to a file path and returns true if it's a .zip file bigger than 1MB that was modified in the last hour. Sure, it is remarkable that no variables are needed for such a program, but it is not very readable: because no variables are used, it is often necessary to make copies of elements and push them to the end of the stack -- that's what the {#link-operator||stack||dup#} and {#link-operator||stack||swap#} are used for.
 
-The good news is that you can use the {#link-operator||lang||define#} operator and the `:` sigil to define new symbols, and symbols can also be set to literals of course.
