Eval() is for expressions, exec() is for general code.  But you do not 
really need a variant.  Just define a preprocessor function 'blockify' 
which converts code in an alternate syntax to regular indented block 
syntax.  Then

exec(blockify(alt_code_string))

I presume that this is more or less what the templating engines do.
