A flex generated scanner could decide to store the entire input file
in memory. That way, a single buffer can be used in several places in
the tool chain that uses a scanner.


Is this an idea that has been explored and thought of as unworthy?


I know that multiple input files could increase the size of the
buffer(s) but hey, we are living in the age of 100s of MB of main
memory.


Sincerely.

RAM in the 1980s. -John]
