I think the problem is that Class::DBI::Join is a Schwern-ism, that no-one else knows much about, and he frequently disappears for months at a time ... My guess is that you don't actually want to be using Class::DBI::Join, but using a combination of the has_many-with-optional-mapping-method functionality of Class::DBI itself, with the has_many taking search arguments.

s/$search/$replace/$parameters
I've been banging my head against a brick wall on and off over this one
now.
I inherited some code that contain the following statement inside two
nested for loops:
eval \$variable_hash-{'$variable'} =~ s/$search/$replace/$parameters;;
I did some benchmarking, and profiling to confirm my suspicions that
eval{} inside for(){for(){ ...}} is slow.
I thought there must be another way.
I found s/(?${parameter}:$search)/$replace/
This was working fine, until I found out that some instances of $replace
contain $1.
e.g.
$search = q[(.+)];
$replace = q['$1'];
$search seems to arrive at the function containing this as a qr'd
regexp.
In this instance $parameters was empty.
In the code I'm fighting with $parameter is usually g or nothing.
If I passed the value 16/07/2002 14:58:09 to the eval() version I
would get: '16/07/2002 14:58:09'
If I pass the value 16/07/2002 14:58:09 to the s///, I get: '$1'
I'd really like to kill the eval() but don't know how to get
$replace expanded in the s/// version.
I've recently realised that you can't have s/(?g:$search)/$replace/ so
I've tweaked my code to check for g in $parameters and do s///g or s///
accordingly.
If anyone has any ideas/pointers/references/solutions I'd really like to
hear,
Chisel

I don't know how you'll get that strategy to work (having $1 in
$replace). /e doesn't seem to help and I'm not sure why.
Anyway, if you're having trouble with for() { for () { eval } } then
move the eval outside, i.e. generate a string that contains the nested
for()s and run that code as a single eval.
