No, better stick to the for(( bashism, it goes in tune with the ${name:0:$i} bashism!
Also seq is an external command, not available in some OS.
These kind of shortcuts are for an interactive shell.
Bash has the tab key for expansions.
The completion stuff as in post#3 is the correct way.

NAME
fish - fish - the friendly interactive shell
fish - the friendly interactive shell
Synopsis
fish [-h] [-v] [-c command] [FILE [ARGUMENTS...]]
Description
A commandline shell written mainly with interactive use in mind. The full manual is available in html by using the help command from inside
fish.
o -c or --command=COMMANDS evaluate the specified commands instead of reading from the commandline
o -d or --debug-level=DEBUG_LEVEL specify the verbosity level of fish. A higher number means higher verbosity. The default level is 1.
o -h or --help display help and exit
o -i or --interactive specify that fish is to run in interactive mode
o -l or --login specify that fish is to run as a login shell
o -n or --no-execute do not execute any commands, only perform syntax checking
o -p or --profile=PROFILE_FILE when fish exits, output timing information on all executed commands to the specified file
o -v or --version display version and exit
The fish exit status is generally the exit status of the last foreground command. If fish is exiting because of a parse error, the exit
status is 127.
