in thread It's so easy to become complacent.

That's why I like to omit the parentheses whenever possible: 
$ perl -E 'use strict; sub foo { say "hello" }; say "runtime!"; foo'
runtime!
hello
$ perl -E 'use strict; sub foo { say "hello" }; say "runtime!"; f00'
Bareword "f00" not allowed while "strict subs" in use at -e line 1.
Execution of -e aborted due to compilation errors.
