Sub-selects can't be avoided, period. Projected expressions can be avoided if assignments are allowed --- just LET a fake variable and return it. Assignments can be avoided if projected expressions are allowed (but macroexpansion of LET may result a huge amount of text). I'd recommend to not choose 20 of 3 as soon as all 3 can be implemented. Developers have enough reasons for headache, an artificial puzzle of weird limitations of the language will not make them happy.
