If you install git (standard download from
git-scm.com), you get "git-bash" (an MSYS based GNU bash), and a perl is included (which could be seen as a "system perl"). Calling the
portableshell.bat of a portable Strawberry from git-bash seems to work in principle (
perl -v gives the Strawberry's version instead of git-bash's), but seems to mess with keyboard settings (arrow-up and down move the cursor/send control characters instead of browsing through the CLI history). I assume one could convert the BAT file into a shell script, which would mitigate this.
