No. glob() returns the files that exists, but only if there exists
at least one. Otherwise, it just does the { } expansion, and leaves
things as is. Just like in *some* shells.
bash $ echo yy*
yy*
bash $ echo y?y
y?y
bash $ echo y{a,e,i,o,u,y,}y
yay yey yiy yoy yuy yyy yy
ksh $ echo yy*
yy*
ksh $ echo y?y
y?y
ksh $ echo y{a,e,i,o,u,y,}y
y{a,e,i,o,u,y,}y
csh % echo yy*
echo: No match
csh % echo y?y
echo: No match
csh % echo y{a,e,i,o,u,y,}y
yay yey yiy yoy yuy yyy yy
