A neat little excerpt.
In fact, we could quantify this phenomenon when we ported some of our components from other languages to F#. In order to remove some legacy dependencies, for instance, we ported a Perl script to a 37% smaller F# program. In a separate effort we ported 1,338 lines of PowerShell scripts to just 489 lines of F# (2.7 times smaller). In both cases, despite the code size reduction, the resulting F# program improved logging, readability and reliability (due in part to static type checking).
