Problem: Using function() with a name will find another function when it is
redefined.
Solution: Add funcref(). Refer to lambda using a partial. Fix several
reference counting issues.
Problem: User defined functions can't be a closure.
Solution: Add the "closure" argument. Allow using :unlet on a bound
variable. (Yasuhiro Matsumoto, Ken Takata)
Problem: Using submatch() in a lambda passed to substitute() is verbose.
Solution: Use a static list and pass it as an optional argument to the
function. Fix memory leak.
Problem: filter() and map() either require a string or defining a function.
Solution: Support lambda, a short way to define a function that evaluates an
expression. (Yasuhiro Matsumoto, Ken Takata)
Problem: When a file gets a name when writing it 'acd' is not effective.
(Dan Church)
Solution: Invoke DO_AUTOCHDIR after writing the file. (Allen Haim, closes
#777, closes#803) Add test_autochdir() to enable 'acd' before
"starting" is reset.
Problem: On MS-Windows large files (> 2Gbyte) cause problems.
Solution: Use "off_T" instead of "off_t". Use "stat_T" instead of "struct
stat". Use 64 bit system functions if available. (Ken Takata)
Problem: When writing viminfo merging current history with history in
viminfo may drop recent history entries.
Solution: Add new format for viminfo lines, use it for history entries. Use
a timestamp for ordering the entries. Add test_settime().
Add the viminfo version. Does not do merging on timestamp yet.
Problem: Cannot use a window ID where a window number is expected.
Solution: Add LOWEST_WIN_ID, so that the window ID can be used where a
number is expected.
Problem: Comparing functions and partials doesn't work well.
Solution: Add tests. (Nikolai Pavlov) Compare the dict and arguments in the
partial. (closes#813)
Problem: string() with repeated argument does not give a result usable by
eval().
Solution: Refactor echo_striong and tv2string(), moving the common part to
echo_string_core(). (Ken Takata)
Problem: Getting an item from a NULL dict crashes. Setting a register to a
NULL list crashes. (Nikolai Pavlov, issue #768) Comparing a NULL
dict with a NULL dict fails.
Solution: Properly check for NULL.
Problem: Using old function name in comment. More functions should start
with test_.
Solution: Rename function in comment. (Higashi Higashi) Rename
disable_char_avail_for_testing() to test_disable_char_avail().
And alloc_fail() to test_alloc_fail().
Problem: Functions specifically for testing do not sort together.
Solution: Rename garbagecollect_for_testing() to test_garbagecollect_now().
Add test_null_list(), test_null_dict(), etc.
Problem: When using a partial on a dictionary it always gets bound to that
dictionary.
Solution: Make a difference between binding a function to a dictionary
explicitly or automatically.
