Fellow monks,

In my current project, I'm using hashes that contain references to all sorts of things and I use arrays to contain the values that these hashes are keyed on: 

@keys = ("key1", "key2");
%list_of_refs = (
   key1 = \%ref_to_hash1,
   key2 = \%ref_to_hash2
);

etc. I found that when using extremely short keys (specifically "v2" and "v3"), the program would not find anything from the hashes that were so keyed. However, when I changed the key names to "ver2" and "ver3", the program immediately behaved completely as expected. Can anymonk tell me why I wouldn't be able to use an arbitrary variable name?

DISCLAIMER: I am not using an IDE, but as far as I know (and I did look for a bit) v2 and v3 are not reserved words in PERL. If this is the case, feel free to chastise...errr...enlighten me :)
