New in version 1.1.
Divide leaves meiotically in expr n times:
abjad> staff = Staff("c'8 d'8 e'8 f'8")
abjad> spannertools.BeamSpanner(staff.leaves)
BeamSpanner(c'8, d'8, e'8, f'8)
abjad> f(staff)
\new Staff {
c'8 [
d'8
e'8
f'8 ]
}
abjad> leaftools.divide_leaves_in_expr_meiotically(staff[2:], n = 4)
abjad> f(staff)
\new Staff {
c'8 [
d'8
e'32
e'32
e'32
e'32
f'32
f'32
f'32
f'32 ]
}
Replace every leaf in expr with n new leaves.
Preserve parentage and spanners.
Allow divisions into only 1, 2, 4, 8, 16, ... and other nonnegative integer powers of 2.
Produce only leaves and never tuplets or other containers.
Return none.
Changed in version 2.0: renamed leaftools.meiose() to leaftools.divide_leaves_in_expr_meiotically().
