Thank you, yes that was silly!
My apologies for the noise.

Of course to make it even stranger
sparql -v "select * where {BIND(substr(str("1234567890"), 0, 11) AS

Does work as expected!
Because the expression is
substr(str(1234567890), 0, 11)
"1234567890" becomes integer 1234567890 due to the quoting. bash allows
quoting in the middle of arguments. Unlike some other OS shells, bash
evaluates quotes before passing to the command.

Dear Jena-Devs,
I believe that the following query
select ?substr where {BIND(substr("1234567890", 0, 11) AS ?substr)}
should return
| substr |
================
| "1234567890" |
instead of the current
| substr |

I take this from reading the spec here.
https://www.w3.org/TR/xpath-functions/#func-substring
If people agree with my reading I will be happy to submit a patch.

Jerven
