Comment (by mnelson4):

 I ran @TimothyBlynJacobs's test, (except with one tenth the iterations
 because I was running out of memory).

 == Summary
 41305.3.diff (latest from @TimothyBlynJacobs) is nearly twice as fast as
 41305.all-in.2.diff​ (latest from @schlessera) and uses 1/3 the memory.

 == Details
 master:
 Time 0.23000001907349
 Memory: 9490200

 41305.all-in.2.diff​ (latest from @schlessera):
 Time 0.62402606010437
 Memory: 57761176


 41305.3.diff (latest from @TimothyBlynJacobs):
 Time 0.28000116348267
 Memory: 20161176

 So, in this test, 41305.3.diff was nearly as fast as master, although used
 up twice the memory. 41305.all-in.2.diff​ was 3x slower and used up nearly
 6x the memory. (Given, this test assumes all strings are evaluated; I
 realize the reason this ticket helps is because most strings are NOT
 evaluated).

 So 41305.3.diff looks like an improvement on 41305.all-in.2.diff to me.

 Note I'm on PHP 7.1.19
