template equal(alias pred = "a == b")

Returns $(D true) if and only if the two ranges compare equal element
for element, according to binary predicate $(D pred). The ranges may
have different element types, as long as $(D pred(a, b)) evaluates to
$(D bool) for $(D a) in $(D r1) and $(D b) in $(D r2). Performs
$(BIGOH min(r1.length, r2.length)) evaluations of $(D pred).
This function compares to ranges for equality. The ranges may have
different element types, as long as $(D pred(a, b)) evaluates to $(D bool)
for $(D a) in $(D r1) and $(D b) in $(D r2).
Performs $(BIGOH min(r1.length, r2.length)) evaluations of $(D pred).
Params:
r1 = The first range to be compared.
r2 = The second range to be compared.
Returns:
$(D true) if and only if the two ranges compare equal element
for element, according to binary predicate $(D pred).
