Local variables for nested function calls

[eduardo-chibas]

Are there other things to be unsatisfied with in addition to
`: "${fdir:="${@:$#}"}"}` and `fdir=${fdir:-default}`.

You are satisfied with

`bar="${foo:-default}`

Would you also be satisfied with

: ${ctx:=8}

Was the problem mostly related to using a list such as `$@` together with the 
other
complications?

Have only started looking about these things a few days ago, so most of my 
analysis
on what to use in specific situations is likely wrong.  That's why I am asking
for some illumination on this list.
