Problem: Vim9: finding global function without g: prefix but not finding
global variable is inconsistent.
Solution: Require using g: for a global function. Change the vim9.vim
script into a Vim9 script with exports. Fix that import in legacy
script does not work.
Problem: Vim9: inconsistent arguments for test functions.
Solution: When :def function and script have different arguments use a list
with two items instead of a separate function.
Problem: Vim9: runtime and compile time type checks are not the same.
Solution: Add more runtime type checks for builtin functions. (Yegappan
Lakshmanan, closes#8646)
Problem: Tests failing because there is no error for float to string
conversion.
Solution: Change the check for failure to check for correct result. Make
some conversions strict in Vim9 script.
Problem: Some balloon tests don't run when they can.
Solution: Split GUI balloon tests off into a separate file. (Ozaki Kiichi,
closes#4538) Change the feature check into a command for
consistency.
Problem: str2nr() and str2float() do not always work with negative values.
Solution: Be more flexible about handling signs. (LemonBoy, closes#1332)
Add more tests.
Problem: On MS-Windows some float functions return a different value when
passed unusual values. strtod() doesn't work for "inf" and "nan".
Solution: Accept both results. Fix str2float() for MS-Windows. Also
reorder assert function arguments.
