As with all compiler switch variables, the value of this variable
can be t, nil, or a
function object that accepts four arguments and returns t or nil. The arguments
passed to the function will be the values of the safety, space, speed,
and debug optimization qualities, in that order. nil is equivalent to a function that always returns
nil and t to a
function that always returns t. When the
value is a function and we say t (or true) or
nil (or false) in the text below, we mean
that the function returns, respectively, t or
nil.
When true, a format string (the second required argument to
format) is converted to a tree structure at compile
time. If nil, the conversion is done at run
time, resulting in slower printing but smaller code. Initially true
when speed is greater than space.
See compiling.htm for information on the compiler.
