int dot;

// doesn't try to use local "int dot"
Immediately looking at only that part of the code, i have to ask
'how the hell are you calling the int???'. Of course i can tell
from your source dot is also a function in the vector.
Considering dot could now shadow the variables or function
names, it would quickly QUICKLY become annoying. A hierarchy of
how the call is used plus the documentation of what it's
obviously doing is a much better approach. Not to mention we've
been using . and -> and * so long for accessing/de-referencing
members that are attached so long that changing it is probably
not an option. MAYBE if you were starting a language from
scratch, but in this case i would firmly say no, this is ugly and
confusing.
