for whatever reason (also probably a bad one), i hate the syntax of switch statements, and for that reason i almost never use them. the match expression though, i'm actually very excited about. i quite like the mapped look; it seems more intuitive to read.
nothing wrong with switch statements.
Coerced-typed (weak) comparisons and easy accidental fallthrough are the problems commonly associated with switch statements.
The new match construct fixes both of these and is also an expression instead of a statement, allowing for more expressive code.
