Scala vs Erlang deconstruction

deconstruct.scala

val (x, y) = (1, 2) // compiles, no errors in runtime

val a = (100, 200, 300)

val (z, w) = a // I doesn't throw an exception, it just will not compile, since the code syntactically incorrect.
               // However Erlang/Elixir will compile it, but throw an exception in runtime.
