You mean a shell with jam syntax, or... ?

This is not a bug, all shells works like this. The golden rule of shell
scripting is that variables should be quoted, unless you know what are
you doing. Differentiating between quoted and unquoted can be called a
feature since with it can be accomplished very cool tricks.

For example (random thoughts), this would be very hard to distinguish
for jam-like shell:

c = ls && pwd ;   # we want 'ls && pwd' string or to execute each of them ?
c = "ls && pwd" ; # more shell like behaviour, this is a string
