[Haskell-cafe] Dynamically linking frameworks on macOS

Hi everyone,

I'm trying to ensure that beginner-level code that uses reflex-dom can be
built by simply calling 'ghc myFile.hs', provided that all the necessary
libraries are available in ghc-pkg.  This works on linux, but on macOS,
it's currently necessary for the user to add '-dynamic' to the command
line.  In particular, without -dynamic, the linker fails to find
"_OBJC_CLASS_$_NSURL", which is a symbol in the Foundation system
framework.  Apple doesn't support (and strongly discourages) statically
linked executables[1], so it's not terribly surprising that this doesn't

Is there anything I can do to avoid the need for -dynamic here?
