Are there any programming languages that extend the behaviour

This syntax is currently disallowed by DMD.
I'm aware of the risk of a programmer misinterpreting this as
if ((low < value) < high)
Is this the reason why no languages (including D allows it).
I'm asking for in some cases, where value is a long expression,
it would be a nice syntatic sugar to use.
I know Coffeescript has them, they are called 'chained comparison
operators' I believe and are a nice syntax cake imo. they are
written as expected:
if 10 < a < 20
