Usually it is enough for me to see the method prototypes to understand
what it does, for example "sub name ($;$)" means object method that is
setter/getter. Functions without prototypes require code examination to be
understood. Since prototypes are unrelable and the function should check
its parameters itself anyway, the main usage is readability.

If you think about a function as a small solid unit that either works or
does not work, it makes sence to predeclare it for external usage and has
no much justification to predeclare it for mere internal usage. Anyway,
since prototypes are ignored for method calls the whole discussion is more
related to scripts/modules than to perllib classes.
