Editing Short-circuit evaluation (section)

===Idiomatic conditional construct===
Since minimal evaluation is part of an operator's semantic definition and not an optional [[compiler optimization|optimization]], a number of coding idioms rely on it as a succinct conditional construct. Examples include:

[[Perl]] idioms:
<syntaxhighlight lang="perl">
some_condition or die;    # Abort execution if some_condition is false
some_condition and die;   # Abort execution if some_condition is true
</syntaxhighlight>

[[POSIX shell]] idioms:<ref>{{cite web |url=https://unix.stackexchange.com/questions/190543/what-does-mean-in-bash |title=What does {{!}}{{!}} mean in bash? |publisher=stackexchange.com |access-date=2019-01-09}}</ref>
<syntaxhighlight lang="bash">
modprobe -q some_module && echo "some_module installed" || echo "some_module not installed"
</syntaxhighlight>
This idiom presumes that <code>echo</code> cannot fail.
