Ehm, you cant *just* use & and expect all to stay the same...
concider the following:
if you use a & you dont need to predeclare a sub if you want to leave of the
parenthesis for an argument list:
ie:
&foo #calls sub foo with no arguments
foo #calls sub foo with no arguments IF you predeclared sub foo
anywhere... if not, its' a bareword
also, and this is more important, if you set up prototyping for your subs, &
will disable prototype checking...
now most of the time you dont set up prototypes so it's unlikely you get
bitten, but the second you change your sub to use prototype's and you do not
leave off the & in your sub calls, they wont get checked
read perldoc perlsub for more information
hope this clears things up,
