Usage
-----
The parameters must necessarily be defined within and at the beginning of the bif "code".
```html
{:code;
{:param; name1 >> value :}
{:param; name2 >> value :}
...
:}
```
The parameters have block scope, will be inherited and recover their value:
```html
{:code;
{:param; name >> 1 :}
{:code;
{:param; name >> 2 :}
:}
{:* "name" will recover their value *:}
:}
```
Example of passing arguments to template:
```html
{:code;
{:param; option >> value :}
{:include; foo.tpl :}
:}
```
Example of passing arguments to snippet:
```html
{:code;
{:param; option >> blue :}
{:snippet; foo :}
:}
```
The snippet may be:
```html
{:snippet; foo >>
The option is: {:param; option :}
:}
```
