Just wanted to add to the below that the problem is not just chaining
functions, but using the return value of the function itself. If the
function returns a dictionary (and probably a list), you can't use it to
access its members, so something like this will also fail:
let t.T()['abc'] = 'xyz'
However, using it in an expression works fine, e.g.,:
return t.T()['abc']

Subject: vim patch: fixing resetting dictionary function
Try this without the fix and you get:
ADD
n=9
Error detected while processing /home/emberson/vim/foo.vim:
line 14:
E475: Invalid argument: 1
ADD
n=9
Note that "1" is the index of the function in the dictionary.
Try it with the fix you get:
ADD
n=9
MULTIPLY
n=20
script:
let x = {}
function x.foo(a,b) dict
echo "ADD"
return a:a + a:b
endfunction
let n = x.foo(4,5)
echo "n=" . n
function! x.foo(a,b) dict
echo "MULTIPLY"
return a:a * a:b
endfunction
let n = x.foo(4,5)
echo "n=" . n
