Subject: Mismatched variable parens/braces works

It’s fairly well known that $() and ${} are both valid for variable
interpolation. However, apparently Cfengine just determines if the opening and
closing delimiters are valid, not whether they match. I don’t know whether this
was intentional, unexpected-but-okay, or a bug, but I happened to find it when
I noticed a typo in a co-worker’s code that nevertheless worked.
bundle agent test {
vars:
"stuff" string => "blah";
reports:
cfengine_3::
"() = $(stuff)";
"{} = ${stuff}";
"(} = $(stuff}";
"{) = ${stuff)";
}
# cf-agent -b test -Kf ./test.cf
R: () = blah
R: {} = blah
R: (} = blah
R: {) = blah
