Comment:

 > Ended up inlining one of the PCRE bindings since rewriting this without
 Perl Regex would have ended up in something a lot bigger and complexer.

 I [https://github.com/Mistuke/ghc/tree/trac-9832-replace-split-perl-
 script-with-haskell 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.

 What is the problem we're trying so solve here? If it's binary size: we've
 been shipping Python and fortran compilers as well, maybe start with
 stripping those (#9014).

 Perhaps we can get rid of split-objs completely? I found the following
 quote by @simonmar in SharedLibraries:

    "Shared libs also completely eliminates the need for the “split objs”
 hack
    that GHC uses to reduce the size of statically linked programs. This
 should
    make our link times a bit quicker."
