It's sometimes interesting to take some measurements of dictionary names.
Determine the number of words in the dictionary.
~~~#0 [ drop n:inc ] d:for-each
'%n_names_defined\n s:format s:put
Determine the average length of a word name.
~~~#0 [ d:name s:length + ] d:for-each
#0 [ drop n:inc ] d:for-each
/ 'Average_name_length:_%n\n s:format s:put
And without the namespaces...
~~~#0 #0 [ d:name dup $: s:index/char n:inc + s:length + [ n:inc ] dip ] d:for-each swap /
'Average_name_without_namespace:_%n\n s:format s:put
Longest name are...
~~~#0 [ d:name s:length n:max ] d:for-each
'Longest_names_are_%n_characters\n s:format s:put
