Implicitly converted to const, yes. That happens often enough, but
immutable?
Anything that does not contain pointers or references to non-immutable
data is implicitly convertible to immutable, if passed by value.
And you definitely don't have to use immutable references with pure
functions.
That sounds like a bug. Unless you mean things like immutable(char)[],
which is implicitly convertible to immutable, according to the above rules.
I have gotten some const-related errors when using pure on member
functions, so
I get the impression that using pure on a member function implicitly
makes it
const, but I'm not sure if that's enough.
The 'this' pointer is also a parameter to a function, so also needs to
be immutable.
