sure. but syntax mistakes are checked at compile time, and when it is
compiled, it will run really fast because since that moment is is machine
bytecode.

parsing config files.. for examle. this is the Puzzle script will help a
lot, there is a subroutine for creating build-order-stageX files, this
will improve speed in those cases.. although in my perl implementation
those schemes won't be used.. since i am trying packages config files like
perl modules, also compiled and loaded to bytecode, and kept in variables
and functions.. u will see..

sure, that's actually the same way as the current bash system, loading
scripts with ". my_bash_source.sh" or "source my_bash_source.sh".. but i
am doing this with something valled packages in perl. the same concept
actually.

i can't help with crossbuilds i guess. dependencies, cool, now i am trying
to implement some way to check this.. the hdw source dependencies, the
build procedures dependencies and of course the packages deendencies

sure. i am using the old experience.

slow! one could see this is those scripts that take some time parsing
files contents and that, running a lot of "grep" commands and that.. not
ideal for high-load scripts..

slower only when compiling.. after that!, it will run as faster as another
binary program. compilation time is not really as slow actually. for me it
is faster, afaikan see.

enough
