No, first Fish checks the syntax. The command you typed is
syntactically incorrect. Fish returns an error message, but not the
one you posted. It says:
fish: Did you mean (COMMAND)? In fish, the “$” character is only used
for accessing variables. To learn more about command substitution in
fish, type “help expand-command-substitution”.
echo $(echo $PATH)
