Hello all,
I am clearly overlooking something basic, but I can't wrap my
head around the parse error in the second command below.
It is apparently caused when the the only contents of a map()
BLOCK is a list without parens.
|| % perl -le 'print map {1; 1, 2} qw(a b)'
|| 1212
|| %
|| % perl -le 'print map {1, 2} qw(a b)'
|| syntax error at -e line 1, near "} qw(a b)"
|| Execution of -e aborted due to compilation errors.
|| %
|| % perl -le 'print map {(1, 2)} qw(a b)'
|| 1212
|| %
|| % perl -v | grep built
|| This is perl, v5.6.0 built for sun4-solaris
|| %
Deparse doesn't help me grok the parse error.
|| %
|| % perl -MO=Deparse -le 'print map {1, 2} qw(a b)'
|| syntax error at -e line 1, near "} qw(a b)"
|| -e had compilation errors.
|| ;
|| %
Any advice on correcting this one-liner would be most
helpful. TIA.
