A common idiom (in the Bash world, which inspired PowerShell's && and || operators) is to conditionally exit a script when invocation of a command fails, along the lines of:

# Assume existence of /somepath and exit, if it doesn't exist.
ls /somepath || exit 1

Currently, neither exit nor return nor throw can be used on the RHS of && / ||

Steps to reproduce

{ Get-Item /nosuch || return  } | Should -Not -Throw
{ Get-Item / && return  } | Should -Not -Throw

Expected behavior

The tests should pass.

Actual behavior

The tests fail, because return is not recognized

Expected no exception to be thrown, but an exception 
"The term 'return' is not recognized as the name of a 
cmdlet, function, script file, or operable program. ..."...
