Andy,
a string and a block are two distinct things in Smalltalk. Seaside
just lets you provide one or the other as an argument for messages
like paragraph: because that's convenient when you write a web
application. Sometimes you want to have plain text in that paragraph,
then you use
html paragraph: 'some text'.
Other times you want to nest more html structures inside the
paragraph, then you do something like
html paragraph: [
html span
class: 'highlight';
with: 'more text'
]
or, maybe more illustrative of the idea:
html table: [
html tableRow: [
html tableData: 'cell 1'.
html tableData: 'cell 2'
].
html tableRow: [
html tableData: 'cell 3'.
html tableData: 'cell 4'
].
]
Somewhere in the Seaside code there is a dispatch that processes
strings and blocks differently.
