- Should we bundle an apr-based "application/xml" parser?
If so, how should we parse the xml data into an apr_table?
+ - For 5.8.1+, the current perl-glue implementation enables
+ MAGIC KEYS for all the @keys = $obj->get() calls. The entries
+ in @keys are scalars with vstring-magic which is survives
+ assignment. The magic contains a pointer to the perl object
+ $obj references, and a pointer to the table value associated
+ with the key. A subsequent call to $val = $obj->get($key[$n])
+ bypasses the normal table lookups, using the magic in $key[$n]
+ to retrieve $val.
+ .
+ I don't know if the faster lookups balance out the overhead
+ of attaching the v-string magic, so it's something that probably
+ should be benchmarked. However the real motivation for this
+ was to provide better support for multivalued keys (since a
+ magic key "knows" which value it's associated with). Whether
+ or not users will appreciate this feature, or find it too confusing,
+ is presently unknown.
