[REBOL] Re: Fast way to strip characters

Hi list,
far from being a parse guru, but here's a bit more hopefully optimised
and easier version :-)
speedtest: func [][
st: now/precise
loop 10000 [
teststring: copy "I'm so not here"
stripped: trim/with teststring "' "
]
et: now/precise
print ["10000 trim/with took:" difference et st]
st: now/precise
strip: charset [#" " #"'"]
loop 10000 [
teststring: copy "I'm so not here"
parse/all teststring [any [here: strip (remove here) | skip]]
]
et: now/precise
print ["10000 parse took:" difference et st]
]
->> speedtest
10000 trim/with took: 0:00:00.018
10000 parse took: 0:00:00.046
PS: without the /all refinement, spaces were not even considered ....
however - by consecutively running speedtest, result times jump here and
there ...
Cheers,
