OpenLink Virtuoso supports "is ... of" syntax for years because it was
easier to parse a wrong resource than to explain that Turtle differs
from N3 and the author of the resource can't write
<#al> is <#child> of <#pat> .
as in
http://www.w3.org/2000/10/swap/Primer

Surprisingly, nobody tried another syntax sugar from the very same
paragraph of same doc, namely
<#pat> has <#child> <#al> .
so nobody noticed that we've discontinued its support.

I'm not sure we really need this syntax now. Nowadays Turtle is much
more popular than N3. But if there's some need in sugar, let it be
"is...of".
