Improve speed of test_tokenize.StringPrefixTest.test_prefixes #134752
Description
Bug report
Bug description:
It takes about 0.5 seconds to run, because it's doing 127,452 eval statements. It could no doubt be sped up, although I might have to sacrifice some completeness. For example, one simplifying assumption is that all multi-character string prefixes must begin with one of the single-character prefix. I guess it's possible that this won't always be the case, but it seems likely to continue.
