Use braces:

level4={[
e4,
/* Level 1 multiplied by Level 3 */
z1*z5,
z1*z6,
z1*z7,
/* Level 2 multiplied by itself */
z2*z2,
z2*z3,
z3*z3
]}

If you want to use \ instead, you need to add it at the end of every lines,
including comment lines and empty lines.

level4=([\
e4,\
/* Level 1 multiplied by Level 3 */\
z1*z5,\
z1*z6,\
z1*z7,\
/* Level 2 multiplied by itself */\
z2*z2,\
z2*z3,\
z3*z3\
])

Cheers,
Bill.
