Missing a write("file.txt",mynumber, "a") shortcut

I know that I can open/close a file and print on it, but sometime I find convenient to use write, especially when the time for opening/closing the stream is irrelevant.

I miss a version of write where I can specify to append instead of overwrite the whole file :-/

It’s already rather short:

open(io -> write(io, mystring), "file.txt", "a")
