They're really the same thing -- Tcl's exec would be a simple transformation
of a cross-platform sh-like syntax into Greg's hypothesized functions. The
pain in Tcl's exec implementation was in providing the functionality across
platforms, not in parsing the sh-like syntax. Then again, Tcl was trying to
run all the way back to Windows 3.1, and Python already gave up on that.
