you can run Pashmak code from string.
look at this example:
eval('println("hello world from string")')
output:
hello world from string
this code is ran from a string.
look at this example:
print('enter some code: ')
$code = read()
eval($code)
output:
enter some code: <input>mem 'hi\n'; print(^);
hi
the above code gets a string from user and runs that as pashmak code.
