Indeed, and resolving this problem had been recorded as the goal of
bug #1570.  Indeed, the issue is complicated by tension between the
in-probability inline function returns and the compiler's propensity
to inline things.

Perhaps, though we would be saving just two tokens ("." and "function"
/ "statement" / ...) for each such shorthand use.  Or one could save
typing effort by supporting explicit abbreviations like "k.stmt(...)"
for "kernel.statement(...)".
