This turns splices that are ignored into compiler errors. Other
alternatives here should also be considered, for example making this
a compiler warning rather than an error. For example, the latest
spork as of a3ee63c137ee3234987dbbca71b566994ff8ae8c has an error of this
kind, but the resulting program does work correctly.
Also disallow splice propagation - code of the
form (+ 1 (do ;[2 3 4]) 5).
These now have semantic menaings that are pretty difficult to
work around. Code that tries to maniuplate user8 and user9 signals
right now may be affected
Comparison between different bracket and normal tuples
will now take into account the delimiter type. This solves strange
non-locality issues in the compiler due to this false equality, and is
more consistent with Janet's otherwise strong equality philosophy.
buffer/blit is difficult to use, and while buffer/push is the easiet
buffer manipulation function to use it only appends to the buffer.
buffer/push-at lets users manipulate buffers at any index - useful
for buffers used as an in-memory databases, for example.
Allow more easily importing modules from custom directories
without jumping through too many hoops. Technically, this was
possible before but required circumventing the built-in module/paths
and was just a hassle.
Also add entries to module/path (and module/add-path) to allow code
like the following.
(setdyn :my-libs "/home/me/janet-stuff/")
(import @my-libs/toolbox)
Intended for things like test harnesses where code might not
be installed to the usual directories.
