always fast and gives conservative correct answers, at the expense of
fidelity on medium and large size structures. for example (hash (iota 15))
gives the same result as (hash (iota 14)).
porting code to sort out which NILs are false and which are
empty lists
switching to scheme-style special forms. however you feel about
scheme names vs. CL names, using both is silly.
mostly switching to scheme predicate names, with compatibility
aliases for now. adding set-constant! to make this efficient.
adding null?, eqv?, assq, assv, assoc, memq, memv, member
adding 2-argument form of if
allowing else as final cond condition
looking for init file in same directory as executable, so flisp
can be started from anywhere
renaming T to FL_T, since exporting a 1-character symbol is
not very nice
adding opaque type boilerplate example file
adding correctness checking for the pattern-lambda benchmark
bugfix in int2str
some cleanup
moving some library code around for size optimization
now using == instead of flt_equals for float comparison, mostly
for hash compatibility
better text representation of infs and nans
removing construction of low-level numeric types directly from strings
adding hash function corresponding to equal
better way to initialize builtins
moving advanced bitvector ops to separate compilation unit
rearranging hash table code so it can be specialized for different
comparison functions
one good way to bloat a piece of software is to add several
ASCII pictures of the mona lisa
that could access the current environment dynamically. It also
differed unnecessarily from common lisp set in this respect.
So now setq is a builtin special form that sets lexical or
global variables, and set is a function that sets global variables.
Rather than eliminate the power of the dynamic set, I extended it
by adding eval*, which evaluates its argument in the current
environment. The justification for this is that the interpreter
is already dynamic enough to allow it with no overhead, so the
ability might as well be exposed.
cleanup; removing some magic numbers
beginning hash tables
fixnums still have 30 bits
moving towards making "guest functions" more opaque; their type is now
just 'builtin
pretty printing some forms better: defun, defmacro, for, label
support *print-pretty*
