Howdy monks,

Recently I've been accustomed to update parrot and try some perl6 as my recreation. Below is a small question I come across when I ramble over it 
C:\parrot>perl6 -e "my IO $fh;"
get_bool() not implemented in class 'IO'
current instr.: 'parrot;PCT::HLLCompiler;command_line' pc 1311 (src\PC
+T\HLLCompi
ler.pir:711)
called from Sub 'parrot;Perl6::Compiler;main' pc 11945 (perl6.pir:173)

C:\parrot>perl6 -e "my IO $fh; say $fh.WHAT;"
IO

[download]
Why does not the second statement toss a error? or is it a feature?

Any guru give me some insight into this question?
Thanks in advance!

I am trying to improve my English skills, if you see a mistake please feel free to reply or /msg me a correction
