Nice talk!
I wonder how many people opt to use shortcuts like those mentioned?

Depends on the types.
List.first([])will returnnilbuthd([])will throw an error, andEnum.count(...)works on any enumerable andlength/1only works on lists (byte_sizeorbit_sizefor binaries andmap_sizefor maps). Plushd/lengthwork in guards where the others do not.But I use the type-specific forms when at all possible to help ensure proper types.
