broken parsing of [ in y command

[Schplurtz le déboulonné]

Binary package hint: sed

Hello,

[ should be considered a normal char in the y command.
but, [ needs a matching ], and the content of [...] is not considered as an intervall.
Something is wrong here.
Other sed (solaris 9 for example) treat [ as a normal char in y command.

according to both info and man page, [ is not special in y command.

examples :
sed -e 'y/[/_/'
sed: -e expression #1, char 6: unterminated `y' command

echo azerty | sed -e 'y/[a-z]/[A-Z]/'
AZerty

echo 'az[erty]' | sed -e 'y/[][a-z]/[)(A-Z]/'
AZ[erty)
