Andrei Alexandrescu:
bool between(T, U1, U2)(T v, U1 lo, U2 hi)
{
return v >= lo && v <= hi;
}
I vote a +1 for between(). One use case:

It also helps in the D translation of Python expressions like:
if foo() and 3 < bar(x) < 5 and ...:
That in D need to be split in more lines unless bar() is pure and
light.

Regarding Phobos, currently one of the features I miss mostly is
an optional template function for the min and max functions:
