Maybe I'm not smart enough for Smart Match ;)

It seems that the operands in Smart Match are swapped to what I expected after reading the docs

Is perlsyn#Switch statements clear??? 

 Most of the power comes from implicit smart matching:
 
    when($foo)
 
is exactly equivalent to
 
    when($_ ~~ $foo)

[download]
($_ was given)

and 

#  $a $b Type of Match Implied Matching Code
# ====== ===== ===================== =============
...
#  Array Regex array grep grep /$b/, @$a

[download]
see perlsyn#Smart matching in detail

so when writing

 given (@a) {
    when (/abc/) {}
}

[download]

I expect this to be tested:  @a ~~ /$b/ in the meaning of  grep /$b/, @$a

Two possibilities:

a) the docs need a rewrite!

b) my brain needs a rewrite! ;)

Cheers Rolf ...still confused...

UPDATE: Sorry personally I think that ~~ is far too overloaden with functionality to be easily understood!!!
