The great feature of instantfpc is that it combines two steps: compiling and
runnning. The other great feature is that it uses a cache directory, so that the
source directory does not get polluted by ppu and executables and that it starts
scripts faster than php, bash etc. This way you get the speed of a compiled
program combined with the ease of use of a script.
If you add the ability to fpc to ignore the shebang line, you are still missing
the important features of instantfpc.
In other words: As long as you don't add the other abilities to fpc too, you
still need instantfpc.

Normally a shebang script does not create files - it can run in a readonly
directory.

To compile use:
instantfpc --skip-run -B hello.pas
 
If you don't like typing so much, define an alias for your shell.
alias ifp='instantfpc --skip-run -B'
