    $\begingroup$ @Mr.Wizard, no, I'm not planning to self answer. Yes, safety is basically the only reason - it would be okay to create a held expression for example. $\endgroup$ Commented Feb 3, 2015 at 15:22
  • $\begingroup$ "I would like to test strings to see if they represent numbers." How strict are we talking here? Do you want the string "EulerGamma" to be considered a number, or are you referring to number in the sense of NumberQ? $\endgroup$ Commented Feb 3, 2015 at 19:30
