Thanks for replies.

This type of style should be named for the first creator or first teller
to have firstly reffered to it, like K&R or Allman.


I made a silly script to find the first writer...
By my script the first person is M[irs]+. eagle.

C:\>FFIND_IF.pl > FFIF.log
C:/Perl/lib/CPAN.pm
C:/Perl/lib/Class/Struct.pm
...
C:/Perl/site/lib/SQL/Parser.pm
C:/Perl/site/lib/Win32/GuiTest.pm

1204 files checked, 34 are printded
