Yes, though in my defense, the bash man page liberally uses the term
"keyword".

Indeed, it appears I enabled expand_aliases. I'll probably reconsider it.

Aliases are not used in bash scripts, unless bash is invoked in POSIX
compatibility mode, or the "expand_aliases" shopt is turned on.
Hi,
#!/usr/bin/env bash
set -eu
alias cmd=echo
cmd() {
echo "$@"
}
set -x
cmd a b c
$ ./a.sh
+ echo a b c
+ echo a b c
...
+ echo a b c
+ echo a b c
Command terminated
Sounds like a bug. I'd expect it to notice the alias, turn "cmd a b c"
into "echo a b c" and print the letters.
