1. Pattern matching

   • Checked from top to bottom

   • Must have one general for fails
   • _ ignores that item
   • as patterns
     • something@(x:y:z)
       • Keeps the whole thing for use

2. Guards

   • Can implement "where"
     • For don't repeat calculs/validations
     • After guards
     • Could be more than 1 variable
     • Could implement pattern matching
     • Syntactic constructs

3. Let

   • Local variables
     • Multiple separated by ";"
   • Expresions
   • Could be used in
     • Lists
     • Tuples
