[bug] Problem with functions -s (string arg) math function & specific input

[Sebastian Gniazdowski <sgniazdowski@xxxxxxxxx>]

Hello,
the contents of the string argument seems to be evaluated in some way
(while it shouldn't). Reproducing snippet:

mtest() { print ${#1}; }
functions -s -M mtest 1 1 mtest
input=') &>/dev/null'
(( mtest($input) ))

Output:
0
zsh: bad math expression: operand expected at `>/dev/null...'
