Yeah I don't think it's about reserved words per se - "IF" isn't a reserved
word either, but is correctly handled (correct IMHO).

From a Oracle SQL Reserved Word prospective you might think so but when
you go to the documentation on Reserved Words, “loop” is not listed.
https://docs.oracle.com/database/121/SQLRF/ap_keywd001.htm#SQLRF55621
Also in testing words it appears to error on the listed Reserved Words,
but some other words that are also fundamental to SQL such as “merge” do
not error either and are not in the key word list.

*Subject:* PL/SQL Interpreter oddity - bug or "expected"?
Ran into this recently, and personally I feel that this should not
compile. What do you guys think?
Simple case in point:
create or replace package foo as
procedure bar;
end;
/
Package created.
create or replace package body foo as
procedure bar
is
begin
begin
null;
end loop;
end;
end;
/
Package body created.
show errors
No errors.
SQL> exec foo.bar
PL/SQL procedure successfully completed.
What is happening is that Oracle interprets the "end loop" as being "end
anonymous_block_name". And in my opinion, with a keyword like "loop" that
should not be happening. In essence, the above is interpreted as:
create or replace package body foo as
procedure bar
is
begin
begin
null;
end anon_block_name;
end;
end;
/
If we switch the "end loop" to an "end if" (which is a similar flow
control keyword) it reacts (in my opinion) correctly:
create or replace package body foo as
procedure bar
is
begin
begin
null;
end if;
end;
end;
/
Warning: Package Body created with compilation errors.
SQL> show errors
Errors for PACKAGE BODY FOO:
LINE/COL ERROR
-------- -----------------------------------------------------------------
7/7 PLS-00103: Encountered the symbol "IF" when expecting one of the
following:
; <an identifier> <a double-quoted delimited-identifier>
The symbol "IF" was ignored.

Would you agree that that should not compile in the first place?
