A thought related to [* *]
I'm using DBIx::Recordset (very nice) in some of my embperl pages.
Because it uses typglobs, I get concerned about scope, and having one
part of page interfering with some other part, expecially if I'm
including multiple embperl files in an EmbperlObject environment, so
I do this:
[* { local (*set); *]
...
[- *set = somerecordsetcall -]
...
do something with *set
...
[* } *]
a) Does this make sense, or am I causing myself unforeseen problems?
b) Might there be a better way to deal with this, by adding some new
[$ construct for instance. Something like:
[$ local *foo $bar $]
...
[$ endlocal $]

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.

This should work, but I am not quite sure if Perl really cleans up the whole
DBIx::Recordset object in this way

Every single file have it's own namespace, so there can't be any
interferences between different files, also Embperl knows about
DBIx::Recordset and makes sure every DBIx::Recordset is closed and cleaned
up correctly at the end of the request.
If you want to cleanup a DBIx::Recordset in the middle of the page, you can
simple say
[- DBIx::Recordset::Undef ('set') -]
