The problem with this fix, and part of what makes the situ
Hi,
amending the previous approach; please find the attached patch: the global
namerefs are followed, and resolved in the function scope. It works as follows:
bash-4.4$ typeset -n v=w; typeset -n w=x; typeset -n x=v; x=4
bash: warning: x: circular name reference.
bash-4.4$ declare -n ref="HOME
Hi,
since we already allow circular refs in the variable_context, the below
answers your request. It means: in the function scope the name references to
existing global variables will be correctly resolved. Please note that using
find_global_variable in global_variable=find_global_variable(new
