The objective this is to make it fairly easy to implement Lisp 1.5 on top of
any of the many [Make A Lisp](https://github.com/kanaka/mal)

### Commentary
What's surprised me in working on this is how much more polished Lisp 1.5 is
than legend had led me to believe. The language is remarkably close to
[Portable Standard Lisp](http://www.softwarepreservation.org/projects/LISP/standard_lisp_family/#Portable_Standard_LISP_)
which is in my opinion one of the best and most usable early Lisp
implementations. I'm convinced you could still use Lisp 1.5 for interesting
and useful software (which isn't to say that some modern Lisps aren't better,
but this is software which is almost sixty years old).

## Other Lisp 1.5 resources
The main resource I'm aware of is the Software Preservation Society's site,
[here](http://www.softwarepreservation.org/projects/LISP/lisp1.5). It has lots
of fascinating stuff including full assembler listings for various obsolete
processors, but I failed to find the Lisp source of Lisp functions as a text
file, which is why `resources/lisp1.5.lsp` is largely copytyped and
reconstructed from the manual.
I'm not at this time aware of any other working Lisp 1.5 implementations.
