You can access named patterns and nested named patterns by dot-indexing into a pattern. For
example, you can access the nested named pattern subdomain by dot-indexing from emailPattern
into domain and then dot-indexing again into subdomain.
emailPattern.domain.subdomain
ans = pattern
Matching:
asManyOfPattern(identifier + ".") + identifier

Dot-assignment can be used to change named patterns without needing to rewrite the rest of the
pattern expression.
emailPattern.domain = "mathworks.com"
emailPattern = pattern
Matching:
local_part + "@" + domain
Using named patterns:
local_part: asManyOfPattern(identifier + ".") + identifier
domain
: "mathworks.com"
