This is because there is a routine DBI::errstr() and therefore it is
possible that you meant to call it and take its return value as the
name of a scalar variable.
Yuk. Fortunately Perl made the right call.
There's no reason to put braces in like that except when necessary to
isolate a variable name in interpolation.
Also, look at the RaiseError property of DBI connections. I gave up
referring to DBI::errstr some years ago.
