[julia-users] Regex(...) vs. r"..."?

[John Brock]

 regex_from_macro = r"\d\d"
regex_from_function = Regex("\d\d") 

julia> regex_from_macro("45")
true 

julia> regex_from_function("45")
false 

julia> regex_from_macro("5")
false 

julia> regex_from_function("5") 
false


Why does calling r"\d\d" result in different behavior than Regex("\d\d")? I 
would have expected the behavior to be identical, but it looks like call 
with Regex(...) always returns false, while r"..." matches as expected.


This is with Julia v0.4.2.
