lex trial
few more benchs
use the main part of the Opal library
really benchmarking
add precision
warmup the core
pass the text as a local var
String#substring() is strangely faster
extract the common multiplier
use strict
try charAt()
two ways
scan with rexexps and char by char
get chars
jut compare comparison methods
begin the comparision
hardcode [a-zA-Z0-9_]
do the actual lexing a bit
spaces
questions?
