#2948: the type of System.Posix.Process.executeFile is not general enough
-----------------------------+----------------------------------------------
Reporter: nr | Owner:
Type: bug | Status: new
Priority: normal | Component: libraries/unix
Version: 6.10.1 | Severity: normal
Keywords: | Testcase:
Os: Unknown/Multiple | Architecture: Unknown/Multiple
-----------------------------+----------------------------------------------
Because {{{System.Posix.Process.executeFile}}} does not return, its return
type should be {{{IO a}}}, not {{{IO ()}}}. This change would make it
possible to use {{{System.Posix.Process.executeFile}}} in a context that
expects {{{IO Int}}} or {{{IO ProcessStatus}}}, for example.
I may well have assigned this bug to the wrong library.
