Hi,

Well,

  m2(m1 1,2,3)

is OK, but

  m2(1, m1 1,2,3)

is not.  Because BNF says

  call_args : command_call      # unparenthesized method call
            | args              # normal arguments - arg[,arg]*
            | ...               # kinda complex rules to allow * and &

This means that you can specify unparenthesized method call in
argument list iff it's an only argument.  It's a syntactical
bonus.  Inconsistent?  Hmm...
