Replace String within Multiple Files

Hi! I started using script recently, which I've found very useful. One pattern I've found myself using is making in-place replacements across multiple files like this:

script.ListFiles("*.txt").ExecForEach("sed -i 's/tpo/typo/g' {{.}}").Wait()

I think it would be nice to have a "ReplaceInEach" function so that I could replace all sed calls with script equivalents. For example:

script.ListFiles("*.txt").ReplaceInEach("tpo", "typo")

Please let me know what you think. Thanks!
