foreach (%h) {} context hash is not compatible with context list
foreach with a hash is usually an error
map { 'xxx' } %h a hash is not a valid parameter to function map
$xxx = ('yyy', 'zzz') context tuple(string, string) is not compatible with context scalar
@l ||= 'xxx' "||=" is only useful with a scalar
length @l never use "length @l", it returns the length of the string int(@l)
%h . 'yyy' context hash is not compatible with context string
'xxx' > 'yyy' context string is not compatible with context float
context string is not compatible with context float
1 cmp 2 you should use a number operator, not the string operator "cmp" (or replace the number with a string)
$xxx == undef context undef is not compatible with context float
my ($xxx) = 1 context int is not compatible with context tuple(scalar)
($xxx, $yyy) = 1 context int is not compatible with context tuple(scalar, scalar)
($xxx, $yyy) = (1, 2, 3) context tuple(int, int, int) is not compatible with context tuple(scalar, scalar)
@l eq '3' context array is not compatible with context string
qw(a b) > 2 context tuple(string, string) is not compatible with context float
%h > 0 context hash is not compatible with context float
%h eq 0 context hash is not compatible with context string
you should use a number operator, not the string operator "eq" (or replace the number with a string)
@l == ()
