Also, it clashes with the implicit parameters extension, and combining
the extension with a user-defined (?) operator resulted in (?) having
a whitespace-dependent meaning, IIRC.
This is perhaps not so crucial anymore, in the time since I stumbled
into this -fglasgow-exts has largely been replaced by more
fine-grained mechanisms, and implicit parameters has become less
If I haven't seen further, it is by standing in the footprints of giants
