`seq` is not standard, but these days it seems to exist on freebsd and
macos (but may not on solaris). however, in bash one can do
 
long_subject="This is a long subject `echo {1..1000}`"

(to expand {1..1000} inside "" one need to "execute" it -- a trick like
set_long_subject () { long_subject="This is a long subject $*"; }
set_long_subject {1..1000} ;: is unecessarily "complex" for this ;/

PS: fwiw with `echo` (shell-builtin) there just one fork(2) is executed;
using `seq` 2 fork(2)s and one execve(2) would be executed (since bash).
