Doing shell scripting in ANY language not designed for shell 
scripting is the same as shooting yourself in the foot with AK-47 
... Whoever does that is just blindly loyal to the language.

Following BASH one-liner will (hopefully) explain my point. -Try 
to implement the following in D, Scala, and any other language 
not made for shell scripting:

history | awk '{print $2}' | awk 'BEGIN {FS="|"}{print $1}' | 
sort | uniq -c | sort -n | tail | sort -nr

It will output 10 most used commands in your shell.
