No, not really:
(top-gdb) disas &main+1 &main+5
Dump of assembler code from 0x453c39 to 0x453c3d:
0x0000000000453c39 <main+1>: mov %rsp,%rbp
0x0000000000453c3c <main+4>: sub $0x30,%rsp
End of assembler dump.

(top-gdb) disas &main + 1 &main + 5
Argument to arithmetic operation not a number or boolean.
The only way I can see to allow general expressions here is to require
a separator which can't happen in any expression in any language
(semicolon probably comes close), or for parse_expression() to consume
as much as it can and set a "end_of_parse" indicator.
But perhaps splitting on comma (after skipping any quoted expression
-- Foo::bar could have multiple parameters) is "good enough"? That
would allow 'disas &main + 1, &main + 5' to work.
