It isn't the perfect solution, but my best friend when it comes to changing parameter list and/or renaming Perl methods is the bash command:

find ... -print0 | xargs -0 grep 'mymethodname'
-or-
find ... -print0 | xargs -0 grep -l 'mymethodname'

I use the first when I want to find all the files and lines containing my method name. I use the second when I just want to see which files have such lines. If you aren't familiar with the commands:

• find recursively searches for files. It has a rich set of options you can use to screen out files you aren't interested in. The -print0 option uses the null character to separate file names so you don't have to worry about quoting file names with spaces.
• xargs passes the file list produced by find to grep. The -0 argument tells xargs to expect a null delimited file list.
• grep - most likely you are familiar with this, but it selects lines containing a regex you provide. If you only want to see the file names, but not the lines, use the -l option.

With all the find options, the command line can be quite long so I usually run it in a shell where I can keep history. That way I can simply recall the command via history, changing the method name as needed.

Best, beth
