A class for implicit values that can serve as implicit conversions. The implicit resolution algorithm will act as if there existed the additional implicit definition:
def $implicitConversion[T, U](x: T)(c: Conversion[T, U]): U = c(x)
However, the presence of this definition would slow down implicit search since its outermost type matches any pair of types. Therefore, implicit search contains a special case inImplicits#discardForView which emulates the conversion in a more efficient way.
Note that this is a SAM class - function literals are automatically converted to theConversion values.
Also note that in bootstrapped dotty,Predef.<:< should inherit fromConversion. This would cut the number of special cases indiscardForView from two to one.
TheConversion class can also be used to convert explicitly, using theconvert extension method.
