If Haskal is that good then...

...then why does GHC requires Perl 5? The answer is here¹:

I ​noticed that this adds 30.000 lines of C and 1700 lines of Haskell. Not sure if that's any better than just bundling Perl on Windows + a 300 line Perl script.

have you ever tried to do any (non-trivial) text processing with Haskell base? it's a serious pain in the butthole; if you are doing some serious job you could just use some pcre binding... but even then, as you can see, the GHC team preferred to stop worrying and use good ol' Perl.
