Equivalent to Perl Use Strict

General Usage
1

Is there an equivalent in Julia of the Perl Use Strict compiler flag? This means that all variables must be declared.
Very useful for the case I just had where I mistyped a variable name when assigning a string value (in Pythin I add) then used a different variable name to operate on it. Use Strict catches typos like this.

I may have asked the same question some time ago…

A variable not in local scope can still be assigned in global scope at any point before calling a function. And, strictly speaking, compilation may not actually happen before that anyway, so I am not sure how this would be useful.
