Is it possible to extent the Template strings so I can add methods to the identifier:
By default I can replace simple variables:
from string import Template
t = Template("${noun}ification")
t.substitute(dict(noun='Egg')) # Output: 'Eggification'
But I wish to extend the identifier with a custom method (e.g. as_b):
t = Template("${noun.as_b}ification") # Desired output: '<b>Egg</b>ification'
I know I can easily do something similar with Formatted string literals but is it possible using the Template strings, like above? I cannot use Formatted string literals because it will not work inside a script, a JSON file or whatever text that contain curly braces.
Essentially I'm looking for something that can offer the Template strings syntax within the Formatted string literals flexibility.
Genshi does exactly that but it doesn't seem to use the built-in string module.
