Help making a map-do/seq-do based code work on emacs 26.3 |

Hello,
I recently published the tomelr package on GNU ELPA that can take in a
plist or alist and return a TOML string.
Now I need to tackle a small problem that makes the package fail at
run-time only on emacs 26.3 (not on emacs 27+) when a plist is passed
to its tomelr-encode function.
Recipe to reproduce failure:
1. Load emacs 26.3
2. Install tomelr from GNU ELPA
3. (require 'tomelr)
4. M-: (tomelr-encode '(:int 123))
Error backtrace
Test test-plist backtrace:
#f(compiled-function (pair) #<bytecode 0x313eed>)(:int)
mapc(#f(compiled-function (pair) #<bytecode 0x313eed>) (:int 123))

map--do-alist(tomelr--print-pair (:int 123))
map-do(tomelr--print-pair (:int 123))

tomelr--print-list((:int 123))

tomelr--print((:int 123))

(let ((standard-output (get-buffer-create (generate-new-buffer-name
(string-trim (let ((standard-output (get-buffer-create (generate-new
tomelr-encode((:int 123))
Expected output:
"int = 123"
Same error on the package's CI for reference:

===
- Is there a function or few of them that I can override so that
(tomelr-encode '(:int 123)) works on emacs 26.3 as well?
- Can I force install map and seq from GNU ELPA on emacs 26.3? But how
can I do that if a user's package.el is installing tomelr.el from GNU
ELPA as a dependency? Also package.el will refuse to install map and
seq because they are already present in Emacs 26.3 core.
