[basex-talk] Unknown function: lazy:cache

Hi Christian, et al, In the process of reading the wiki and trying examples, I've stumbled across a problem while attempting the lazy:cache example[1] let $f := 'lazy.txt' let $t := lazy:cache(file:read-text($f)) return(file:delete($f), $t) throws an error "No namespace for 'lazy:cache'." If I prepend a `declare namespace lazy = "http://basex.org/modules/lazy";` to the beginning of my test file, I get an updated error: "Unknown function: Q{ http://basex.org/modules/lazy}cache". I get that same result in BaseX-latest (9.0 beta b5f1824) and v8.6.7. Is this a bug or is this A Case of The Missing Import Module Statement? Thanks in advance for your help. Cheers, Bridger [1] http://docs.basex.org/wiki/Lazy_Module#lazy:cache
