From :help :bar you can see that :function is one of the Vim commands that cannot be separated by a | character to chain commands together.

Unfortunately, unlike most Vim commands, this does not work:

:execute "function Meow()" | echom "Meow" | endfunction

You need to use this workaround for one-liner functions:

exec "function Meow()\nechom \"Meow\"\nendfun"

You can also just type the function one line at a time; Vim goes into some special mode when you run the command ":function Meow()" by itself, which is ended when you enter the ":endfunction" command.

Note that the normal use of functions, is in a script file, where you use multiple lines.
