The reason I like hitching a ride on strict vars is that it cuts down
the number of rarely used pragmas people have to remember, yet provides
a way to get to the point where we might, just maybe, someday, make
local lexicals the default for everyone, without having useless pragmas
wandering around various programs, or using up another bit in $^H.
