semicolon support

[isaeken]

now we can use like

func(a+b);
5 + 5;
"hello world";

the evalute method returns when semicolon exists: [(func result), 10, "hello world"]

i like the idea of support for multiple expressions, it would make SMPL a little bit closer to an actual programming language :) but returning all expressions results in an array doesn't seem very useful imho.

what do you think about behavior similar to Ruby's where the last expression's result is returned?

[isaeken]

we can add return instead and no data such as void will be returned unless return is used.

let me elaborate on this:

take a look at the following project that depends on SMPLang: https://github.com/leongrdic/php-dataplater

SMPLang should continue supporting single-expression execution without the return statement, which is why I am considering the Ruby approach. also, multiple expression support doesn't seem very useful without a way to set var values within the language.

i think implementing all of this at this stage is a lot of work and even then i'm not sure it'd be worth the effort.
