The Wrong Question

       "So apparently an eval block is 
        significantly faster than
        calling eval() on a scalar."

• Yep, benchmarks show that it's 170 times faster

• But that's because it doesn't actually evaluate anything

• Whoops

• If you have code in a string, and you want to execute the code, you must use 'string eval'

• Asking whether string or block eval is faster is The Wrong Question

  • It's like asking whether a screwdriver is faster than blinking your eyes

  • You can blink your eyes a lot faster than you can use a screwdriver

  • But it won't help you get that screw in
