I have a shell script with a syntax compatible to both bash and zsh, except for a section that has zsh specific syntax that throws syntax errors if sourced from bash. Is there an easy way to escape such section when using bash?

The script is a bash function that sources all the files in a directory. It works fine from zsh (and it is irrelevant to the question).

#!/usr/bin/env bash

shell=$(ps -p $$ -oargs=)

if [ $shell = "bash" ]; then
	for f in ~/.functions.d/*.sh; do source $f; done
elif [ $shell = "zsh" ]; then
	for f (~/.functions.d/**/*.sh) source $f
fi

The error raised when sourcing it in bash is:

scr: line 8: syntax error near unexpected token `('
scr: line 8: `  for f (~/.functions.d/**/*.sh) source $f'
