How to place cursor after lines appended in function

Question

I have, for many years, used Vim. Until today, I've not found the need for writing my own functions. I found myself faced with adding some features to existing code, and in so doing needed to maintain a pattern. To make life easier, I wrote

function! CompConst()
    let constName = toupper(input("Compiler Constant: "))
    let defBlock = ['#define ' . constName . '_SUFFIX_1',
                \'#define ' . constName . '_SUFFIX_2',
                \'#define ' . constName . '_SUFFIX_3',
                \'#define ' . constName . '_SUFFIX_4']
    call append(line('.'), defBlock)
endfunction

imap <C-d> <C-o>:call CompConst()<cr>

The function works marvelously except ... the cursor is left above the lines just inserted. Yes, this does make sense because I'm using append(). I looked through the help and insert() seems to apply to lists. I haven't yet found a function for inserting text at the current line number. Googling for insert functions and insert just reveals a whole lot of hits for the Ex commands. I even tried a bit of sleight-of-hand and used call append('.-1', defBlock) which did the same as what's above.

If it matters, I'm using Vim 8.0 with patches 1-1453.

Have you considered modifying the function to move the cursor after the list insertion? This worked in my Vim (v8.1.7777)

function! CompConst()
    let constName = toupper(input("Compiler Constant: "))
    let defBlock = ['#define ' . constName . '_SUFFIX_1',
                \'#define ' . constName . '_SUFFIX_2',
                \'#define ' . constName . '_SUFFIX_3',
                \'#define ' . constName . '_SUFFIX_4']
    call append(line('.'), defBlock)
    norm! 4jo
endfunction
