Thank you, I missed the read-only part when reading about a:var
The :help a:var does say "However, if a |List| or |Dictionary| is
used, you can change their contents."
I found this example function. Is {a:var} now a Dictionary?
function! Inc(var)
let {a:var} += 1
return {a:var}
endfunction
Is one better than the other?
function! Inc(var)
let var = a:var
let var += 1
return var
endfunction
