Amazing array intrinsics
Array operations (such as sum) are usually handled by inlining assembly rather than calling a procedure. This allows to write very concise and readable but extremely fast code.
Fortran allows slicing arrays without actually creating a copy. Array is a basic language element and compiler can optimize operations to be blazing fast.
Fortran is very old and many ancient parts of the language are still present in the standard for backwards compatibility which allows writing horrible and unmaintainable code.
