Abstract:
Implicit conversion to and from other types are useful, and is to some
extent covered by existing language features. Some cases are currently
not covered, but could be worthy additions to the toolbox.
I've tried to figure out good ways to add some sorely-needed implicit
conversions to the language, but I'm sure there are details that need
to be ironed out. In other words - destroy!
Although implicit conversions have some usecases, genrally they cause
more damage then help.
One could use suggested mechanism for defining
covariance/contravariance for user types, but it would be too adhoc and
fragile.
