depend on what some understoods by clearer - imo not

this []{;;;} at least is like logically drawed from other c syntax

and switch case overally the word case is ok imo but the word switch is
overrally like wrong imo switch could be better replaced by two
word "select" and maybe "goto" as this swich that selects could use 
select and this one wgo does goto could use word goto

goto key;
'A': printf("a");
'B': printf("b");
'C': printf("c");
'

overally thete is lso possibility to do it such way

void foo()
{

"a" { printf("aaa"); } //definitions not calls itself
"b" { printf("bbb"); }
"c" { printf("ccc"); }


"a";"b";"c"; //calls (???)
// would need maybe some some syntax to call it (many could be chosen)

// "a"() ? foo."a" ? foo.[key] ?

maybe this woudl be the best if established as ths is more syntaktc "low 
lewel"
