Interesting. Do these examples capture the issue you have in mind?

bash-4.2$ gawk '@namespace "ns"; func foo() {print "hello"} BEGIN {for (i in 
FUNCTAB) print i; for (i in PROCINFO["identifiers"]) print i}' | grep foo
ns::foo
ns::foo

bash-4.2$ gawk 'func ns::foo() {print "hello"} BEGIN {for (i in FUNCTAB) print 
i; for (i in PROCINFO["identifiers"]) print i}' | grep foo
ns::foo
ns::foo

bash-4.2$ gawk 'func awk::foo() {print "hello"} BEGIN {for (i in FUNCTAB) print 
i; for (i in PROCINFO["identifiers"]) print i}' | grep foo
foo
awk::foo

bash-4.2$ gawk 'func foo() {print "hello"} BEGIN {for (i in FUNCTAB) print i; 
for (i in PROCINFO["identifiers"]) print i}' | grep foo
foo
foo
