It's not just function calls. Arrays and hashes require no whitespace
between the name and the subscript unless you use the dot form.
@a[0] # ok
@a.[0] # ok
@a [0] # WRONG
@a .[0] # ok
%h{'k'} # ok
%h.{'k'} # ok
%h {'k'} # WRONG
%h .{'k'} # ok
%h<k> # ok
%h.<k> # ok
%h <k> # WRONG
%h .<k> # ok
Also note that the dot follows the subscript so that the following are
also incorrect:
foo. () # WRONG
@a. [0] # WRONG
%h. {'k'} # WRONG
%h. <k> # WRONG
Unless I'm completely mistaken, in which case someone had better
correct me :-)

I didn't really realize that there was a p5->p6 porting guide until I
saw this. I'll add something to the guide as above (plus subs).
