I noticed more than once that the exclamation "!" is used

means?
The binary ! operator is used for specifying template
arguments. I have some explanation here:

I noticed that filter is using the concept of templates but this
time it's with a lambda function, not with a data type, how can
we explain this? isn't supposed to use a data type after the
exclamation mark: "auto r = chain(a, b).filter!(a => a > 0);"
