Another (faster) way to eliminate punctuation would be to keep only those
characters you care for as in:
punc=:a.-.' ',(,(a.i.'Aa')+/i.26){a.
txt=:1e6$'apples, beer and oranges (and not beef) '
(6!:2)'('' '',each pref) +/@E.every < ;:^:_1 ;: txt'
0.364503
(6!:2)'('' '',each pref) +/@E.every <txt-.punc'
0.0349807

Re: [Jprogramming] counting all occurrences of static list ofprefixesin
string
Is this of concern?
text =: 'we grappled with apples,beer,oranges, not beef or alsorans'
pref +/@E.every < text NB. confused by grappled & alsorans
2 2 2
... or are you happy with an approximate count?
Since your prefix list is static you could prepend a blank to each,
and remove punctuation in the text by, for example,
;:^:_1 ;: text
yielding the longer-winded
(' ',each pref) +/@E.every < ;:^:_1 ;: text
1 2 1
