Example compilation issue with template spec

[kerautret]

Probably from the 10.15.4 update with last Xcode I get this error:

Is that not a duplicate of #1437 ? (the __is_forward_iterator requirement that fails)

[rolanddenis]

Yes it is, same file, same line. Closing...

Sorry @rolanddenis I miss it.
